The Guide To Astrophotography With A DLSR

Astrophotography With A DLS

Getting started in Astrophotography is easier than you think but mastering it will take a life time. This is a guide for beginners or people with a small amount of experience. I’ll be focusing on taking pictures with nothing but DSLR cameras and regular lenses. No telescope required!

Deep Sky Astrophotography with a dSLR

In early 2004 Kodak announced it had stopped producing Technical Pan 2415 black-and-white film, widely regarded as the best film for astrophotography. Many of us were left with a choice — either stockpile whatever rolls of Tech Pan we could find, or make the transition into the digital age. At the time I wasn’t ready to invest large sums of money on a CCD camera and the required accessories. While I mulled over these choices, Canon announced an astrophotography version of their popular EOS 20D digital SLR camera. After much contemplation, I decided that this EOS 20Da (S&T: November 2005, page 84) was the best choice for me, and I have never looked back. Read More…

Astrophotography Tutorial

Astrophotography is a hobby rapidly gaining popularity thanks to the fast advancing CMOS sensor technology. Over a decade ago, the light recording material employed in astrophotography was primarily chemical emulsion. Its low sensitivity makes it very hard to record the weak signal from deep space. In addition, the lack of real-time feedback is a huge source of frustration for beginners. Operational errors such as out-of-focus can only be realized after several nights of hard work after the film is developed. Read More…

The Best Telescopes For Beginners Under $200

The Best Telescopes For Beginners Under $200

Telescopes, are eyes for the astronomers, which give them the divine view of the world above. A good telescope is the most important tool for a budding astronomer to make his/her mark in the industry. Telescopes which can be defined as optical instruments used to make distant objects appear nearer, actually work on a simple mechanism of collecting and focusing rays of light from the object and in turn making them appear magnified. They are actually windows to the universe and have made the world above us come alive. The first known telescopes were invented in Netherlands during the 17th century and thereafter there has been no looking back. There are endless options available and one can choose a telescope which best suits his/her purpose. Choosing the right telescope amongst the vast array is a demanding and challenging task. Before buying a telescope one should be clear about these four questions- what one wants to observe? How one wants to observe? Where one lives? And where he/she will be observing? Then these questions need to be weighed in connection to the attributes of the telescope selected,in order to find the best match.

Looking at the night sky through a telescope can be the most amazing feeling, as it transcends you to a new world full of imaginary objects. Initially buying a telescope with a very good scope remained out of budget for most of the people, but now with the advent of digitally-driven manufacturing technology, telescopes of high quality and great capacity are available at affordable prices. In this article we shall be assessing the attributes of certain telescopes which fall under the preview of best telescopes for beginners under $200 and are highly recommended by customers on amazon.

Comet fragments, not aliens, best explain mysterious dimming star

Star and shattered comet
Was it a catastrophic collision in the star’s asteroid belt? A giant impact that disrupted a nearby planet? A dusty cloud of rock and debris? A family of comets breaking apart? Or was it alien megastructures built to harvest the star’s energy?

Just what caused the mysterious dimming of star KIC 8462852?

Massimo Marengo from Iowa State University in Ames wondered when he saw all the buzz about the mysterious star found by citizen scientists on the Planet Hunters website. Read More…

Search for ‘Missing’ Carbon on Mars Cancelled

curiosity rover approaching mars concept
It may be time to call off the search for Mars’ missing carbon.

Mars’ carbon-rich atmosphere was once thick enough to raise the planet’s surface temperature and allow entire oceans of liquid water to form there — a drastic change from the cold desert it is today. This metamorphosis of the Red Planet has put scientists on the hunt for a left-over “carbon reservoir” in the planet’s dirt and soil. So far, the has come up empty. Read More…


Mars May Become a Ringed Planet Someday

mars rings
Mars may one day have rings similar to Saturn’s famous halo, new research suggests.

In a few tens of millions of years, the Red Planet may completely crush its innermost moon, Phobos, and form a ring of rocky debris, according to the new work. Phobos is moving closer to Mars every year, meaning the planet’s gravitational pull on the satellite is increasing. Some scientists have theorized that Phobos will eventually collide with Mars, but the new research suggests that the small moon may not last that long. Read More…

Mystery Signal from a Black Hole-Powered Jet

Blazar jet illus NASA JPLCaltechST
Observing a blazar is a little like standing beneath a relativistic waterfall. Look up: that flickering point of light is a head-on view of the powerful plasma jet shooting out from a supermassive black hole.

The free-flying electrons within that mess of plasma twirl at almost light speed around magnetic fields, and they radiate across the electromagnetic spectrum, often drowning out any other forms of emission. We might even see a sudden outburst when turbulence, a sudden influx of plasma, or some other force roils the jet. Read More…

Scientists get first glimpse of black hole eating star, ejecting high-speed flare

glimpse of black hole eating star
An international team of astrophysicists led by a Johns Hopkins University scientist has for the first time witnessed a star being swallowed by a black hole and ejecting a flare of matter moving at nearly the speed of light.

The finding reported in the journal Science tracks the star — about the size of our sun — as it shifts from its customary path, slips into the gravitational pull of a supermassive black hole and is sucked in, said Sjoert van Velzen, a Hubble fellow at Johns Hopkins.

“These events are extremely rare,” van Velzen said. “It’s the first time we see everything from the stellar destruction followed by the launch of a conical outflow, also called a jet, and we watched it unfold over several months.” Read More…


The Technical Aspects That Make a Good Telescope

Technical Aspects That Make a Good Telescope

Telescope is an instrument that increases the periphery and visual sense of the eyes. When one decides on to buy a telescope one has to do meticulous homework in regards to the various technical aspects of the telescope and then zero into the one which would suit the specific needs. The need to understand the technicality arises from the fact that an amateur astronomer would not be wanting something which is an advanced space telescope and thus waste monetary resources.

A telescopes technicalities can baffle one and the decision as to which one is best suited to ones needs does not come easy. A veteran astronomer and an amateur astronomer would look for different features in their telescopes and thus understanding the functions and technicalities helps by fitting the right block at the right place.

Let’s take a look at the basic technical aspects that make a good telescope which can help one adjudge which telescope is best suited for his/her sphere of work:


The aperture of a telescope is basically the diameter of the mirror or the main lens of the telescope. The aperture determines how bright and sharp view one will get or to say- as the aperture of a telescope increases the view through it becomes sharper and brighter. This notion in literal sense would lead one into believing that, to have a good telescope just have the one with high aperture, but this contention is not true. When one is choosing the right telescope for himself/herself, one should take into consideration his scope of work and the fact that whether the telescope will suit the work environment. For instance if one buys a huge telescope, so as to have a good size of aperture and he/she needs to carry the telescope every-day to various places, then the decision would stand wrong. So what is important is to understand the work practise which one will follow and then choose a telescope with technical aspects best suited to individual needs.

Magnification or Power

The magnification capacities of a telescope is determined by the fact that how close a view of the celestial objects can the telescope offer. The power of the telescope to offer a good magnification is an important technical factor when one is choosing the right telescope for himself/herself, but the fact remains that it is not a decision making factor.

When an astronomer buys a telescope the sole aim which stands is to get a close look at their objects of interest, thus magnification capabilities of a telescope are critical to decision making, but the important aspect is that any telescope’s magnification power can be increased by using different eyepieces. These eyepieces are basically removable lenses which one looks into to get the view. When one buys a telescope he/she generally gets along with it a range of eyepieces and if not a variety of them are available in the market. So this technical aspect can be taken care of and is not much of a concern.

Though a fact remains that just using a high power eyepiece would not give you the desired magnification, till such time it is not supported by proper aperture. So if one uses a high power lens in a telescope with small aperture the view will be magnified but fuzzy. Thus while one chooses a telescope the various technical aspects should be well coordinated for best results.


As we know that all the cars perform the same task of transporting people from one place to another but what differentiates one brand from another is their design. Similarly among telescopes too the designing determines their portability, economies and visual sharpness. Telescopes with similar aperture can also differ in price and portability depending on their designs. Thus design of a telescope is a technical aspect which needs to be looked into while making the buying decision.

On basis of their designing, the telescopes are categorized into three categories:

1. The Refracting Telescope

In a refractor telescope, there is a thin, long tube through which the light passes from the front objective lens in a straight line, to the eyepiece at the opposite end. This is the most commonly used type of telescope and is very simple in design. The best part about this telescope is the fact that since the tube is sealed the optics are protected and little maintenance is required. A refracting telescope provides excellent views of planetary and binary stargazing.

These telescopes have an aperture of 3 to 5 inches and thus are not very suited for gazing distant galaxies. Their portability is also a matter of concern as they are quite bulky and long which restricts their practical use. The refracting telescopes are also quite a burden on the pockets.

2. The Reflecting Telescope

A reflecting telescope works on a different mechanism where a parabolic mirror is used instead of a lens to focus light to a flat secondary mirror, which in turn performs the task of reflecting the image out of an opening located at the main tubes side. This telescope has the advantages of easy construction and thus is easy to use. This telescope gives excellent view of remote galaxies and delivers good quality bright images. It is quite portable and is pretty economical.

Since the tube of this telescope are open in the air it catches dust easily requiring more handling care and maintenance. This telescope is not apt for terrestrial applications and this limits its scope of work.

3. Catadioptric Telescope

This is the most popular type of instrument, where a combination of lenses and mirrors is put to use to form an image. This type of telescope is compact, durable and versatile and provides excellent lunar and deep sky observations. On the other hand it generates a great pocket pinch and doesn’t have a very appealing appearance.

So these are the three kinds of designs for telescope which are segregated on the basis of their technical aspects. One should choose what best suits his/her personnel needs.

Telescope Mounting

Mounting in crude terminology is the base on which a telescope stands, which helps in having that perfect view without any disturbance. Mounts for a telescope can be classified into two types:

THE EQUATORIAL MOUNT – This mount makes your tracking of motions quite swift and easy and is quite advantageous when one is aiming to find his/her way among the stars.

THE ALTAZIMUTH MOUNT – This mount is simpler as compared to equatorial mount giving an up-down, right-left motion. This mount is light in weight and quite low in cost.

These are some of the technical aspects which should be taken into consideration while one is deciding as to which telescope to buy. These technical aspects should be compared with the needs and work of the user, so that the ultimate choice of the telescope turns out beneficial for the one using it.


What is the difference between Refractor and Reflector telescopes?

The Difference Between Refractor and Reflector Telescopes

I am planning to buy a telescope for amateur astronomy, but there’s some confusion between reflector and refractor telescopes. Which one is better? Also, what other factors should I consider for a good telescope?

Reflector and Refractor Telescope Difference

Refractor telescopes are telescopes that use lenses to gather and focus light. Refractors deliver sharp, high-contrast images with crisp views of the moon, planets and stars. Refractors are known for their rugged simplicity. They are easy to aim, they need little maintenance and lenses rarely need alignment-very popular for beginning students of astronomy. Read More…

The Difference Between Refractor and Reflector Telescopes

Refractor VS Reflector Telescopes

The two types of telescopes are quite simple to tell apart. Refractor Telescopes use lenses, much like your regular eye glasses. Reflector Telescopes use mirrors. Both are very great tools for viewing space, but there are some key differences.

Refractor telescopes are almost always very long and slender in size and shape. The eyepieces is always at the bottom of the telescope, putting your view straight through the lenses that are place on the back and front of the telescope. Read More…

Refractor or Reflector – Which is “Best” for Astrophotography?

Who dares to ask that question? Why there have been many spirited debates on the subject, which have discussed every detail and nuance of the question. Many times these debates only serve to fan the flames of the opposing camps. It is not my intention that this thread would have any such effect. My hope is that we can bring out the relevant points of comparison to help in choosing a telescope for astrophotography. Either design has its place in astro-imaging – the two designs are complementary and not necessarily in competition. It’s also worth noting there may be differences in how we answer the question, depending upon whether we are viewing or photographing our subject. Also it matters if we are photographing a wide view or narrow view (like planets). Read More…



The Beginning Of Astronomy

beginning of astronomy

Mankind has long gazed toward the heavens, searching to put meaning and order to the universe around him. Although the movement of constellations — patterns imprinted on the night sky — were the easiest to track, other celestial events such as eclipses and the motion of planets were also charted and predicted.

Astronomy 101 – Early History of Astronomy

The study of our Universe is not new, the history of astronomy shows it to be the oldest science. People have been looking up, trying to explain the universe for as long as there have been people. The earliest Astronomers were priests and holy men, studying the movement of celestial bodies to determine celebrations and planting cycles.
Looking back in history, the ancient Greeks were the first to start developing theories about the design of the Universe (early science of astronomy).

Previous observations of the moon had already led to the knowledge that the Earth was round. When coupled with Plato’s assertion that the sphere was the perfect geometrical shape, the original Geocentric, or Earth-Centered view of the Universe was formed.

While many earlier observers in history believed the heavens were a giant bowl covering the Earth, this new philosophy, expounded by Astronomer Eudoxus and Philosopher Aristotle in the 4th century BC, said the sun, moon, and planets hung on concentric spheres, all surrounding the Earth. Read More…

The Ancient Greeks were the driving force behind the development of western astronomy and science, their philosophers learning from the work of others and adding their own interpretations and observations.

In many older textbooks, the Ancient Greeks are often referred to as the fathers of ancient astronomy, developing elegant theories and mathematical formulae to describe the wonders of the cosmos, a word that, like so many others, came to us from the Greeks.

In fact, this assumption is incorrect and, whilst the Ancient Greek astronomers made huge contributions to astronomy, their knowledge was built upon the solid foundations laid by other great cultures. The Mesopotamian and Zoroastrian astronomers and astrologers, in the Fertile Crescent and the empty deserts of Persia, made many sophisticated observations and devised complex theories to describe cosmological phenomena.

Greek Astronomy

Astronomy is an area where the Greeks displayed a remarkable talent. Observational astronomy, which was the main form of astronomy elsewhere, was taken a step further in Greece: they attempted to build a model of the universe that could account for the observations. They explored all imaginable alternatives, they considered many different solutions for the various astronomical problems they came across. They not only anticipated many ideas of modern astronomy but also some of their ideas endured for around two millennia. Even at the time of Isaac Newton, some aspects of Aristotelian cosmology were still taught at the University of Cambridge.

Our knowledge of Greek astronomy before the 4th century BCE is very incomplete. We have just a few surviving writings, and most of what we know are references and comments form Aristotle, mostly opinions he is about to criticize. What is clear is that the earth was believed to be a sphere, and that there was an increasing effort to understand nature in purely natural term, without recourse to supernatural explanations.

History of Astronomy — The Romans

The Romans. The first Roman calendar was said to have been created by Romulus at the founding of Rome in 753 B.C.E. The original Roman calendar was based on the lunar month, and the year was thought to contain ten lunar months. Later, Numa Pompilius added the months January and February (Januarius and Februarius). Tarquinius Priscus (616-579 B.C.E.), an Etruscan king, made further refinements. His calendar was 355 days long, with an extra month after February every two years. This extra month was at first called Mercedinus, “payment for work,” and was a time when land leases were paid. Later, this extra month was known as Intercalans. The Pontifex Maximus would determine the length of Intercalans, to bring the calendar in line with the Solar Year. Read More…

Astronomers and spaceflight programs also contribute to the study of our own planet, when missions primed at looking outward (or travelling to the moon and beyond) look back and snap great pictures of Earth from space.

A Buying Guide To Pick Best Telescopes For Beginners

best telescopes for beginners

Our universe is immeasurable and vast but with the help of telescopes, one can look at far corners with ease and simplicity. Gazing into the night sky offers a wide number of strange and wonderful sights that can only be cherished for a lifetime. If you love to watch the famous constellation, stars and planets twinkling and gradually moving towards the horizon or illuminating the sky in varied colors, then get the right kind of best telescopes for beginners.

When one is required to buy a telescope, ‘high class’ devices are mostly preferred but people fail to understand to assess their need. A telescope comes in various variety and amazing capability at various price points. It is not necessary to go for the high class and expensive telescope when you have to just perform simple night gazing tasks. Or buying a simple and inferior telescope for your special and dedicated night sky gazing tasks will not do any justice at all. First of all, understand your needs and the types of telescopes available in the market.

The different types of telescopes

In order to pick from the best telescopes for beginners, understand the features and advantages of four distinct types of telescopes. The four types of telescopes are reflector, refractor, hybrid and dobsonian.

• Reflector Telescopes

Reflector are the best telescopes for beginners as it possess a bigger aperture, respectable optics along with a easy set up functionality. Beginner will easily be able to mount the reflector telescope with ease and it bigger aperture will allow to see more of the night sky and smart optics will offers better clarity and precision of the vision.

• Refractor Telescopes

Refractor telescopes come with excellent quality of optics; it can easily be linked with computers and requires lower maintenance. It offers an advantage of using both during the night and daytime with better viewing experience.

• Hybrid Telescopes

Hybrid telescopes are known for their compact design, a beefy mount set up and higher precision of vision to the users. It is one of the best telescopes for beginners that can be used both during the day and night times with same precision and vision clarity.

• Dobsonian Telescopes

Dobsonian telescopes are for those who are looking to perform some rigorous night sky gazing tasks. These telescopes comes with a big aperture which offers bigger avenue of gazing through the sky and it also makes it easier to find targets with it.

How To Choose The Right & Best Telescopes For Beginners?

In order to decide which one will be best telescope for yourself, you have to take various factors into consideration which includes the place you live, the place you wish to explore and how will observe the sky itself. All the above-mentioned telescopes are great for gazing and exploring the night sky. If you wish to use the telescope for bird watching, opt for the Refractor or a hybrid telescope as both of them offers daytime gazing solutions. Both of these telescopes present the image on the right hand side, which will make it easier to track the movements of a moving target like bird.

Maintenance Factor In Telescopes

Maintenance is another factor, which is worth discussing, as all kind of telescopes requires a certain amount of care from the part of the users. The refractors and hybrid telescopes comes with closed tubes but the optics is known to accumulate little bit of dust over the time which can cleaned easily with help of cotton fabrics. Another thing worth noting is that the air can easily circulate in these two telescopes which allows it adjust and adapt with changing temperature swiftly. These telescopes are also able to keep the image distortion at lower side.

Refractor and Dobsonian telescopes require the users to adjust the line of sight, in simple terms, ‘collimate’ the mirrors from time to time. It is not a hard thing to do but one has to adjust it often for getting better vision. A hybrid telescope doesn’t need much collimation and Refractor happens to be among the best telescopes for beginners as it simply does away with the adjusting of line-of-sight completely.

Understand the Aperture

Aperture is the opening present in the telescope that allows the light to enter inside in order to frame images. Each telescope comes with a definite aperture size a large size means more are can be viewed through the telescope while smaller results in vice versa. The buyer mostly prefers wider aperture or larger aperture as it offers sharper focus and brighter images.

It should be noted that telescope job is not just to magnify the targets but also funnel the light photons in such a manner that it offers better assembling of images. The best telescopes for beginners should be the one that offer better images and wider area to focus upon while gazing at the targets.

Consider the Option of ‘Computer Control’

Nowadays, most of the best telescopes for beginners come with a simple on-screen on board computers that allows users to pinpoint on the targets with ease. Having computer control makes it easier to find and point at the targets, which helps in saving a lot of time and minimizes the effort.

With the old-fashioned telescopes or telescopes devoid of computer control, a user has to struggle with reading the start charts and finding objects in the changing night sky. However, with telescopes having computer control, this frustration coming from the inability to pin point the celestial targets are simply erased away.

Some of the astronomers disagree with the usage of computer control in the telescope as it makes the task of star gazing too easy for the beginners. But you are certainly not here for such intellectual and hardcore astronomy gigs; therefore, it is better to buy best telescopes for beginners with computer controls.

If you wish to follow the path of old school with telescopes devoid of computer control, you will have to devote a large amount time that will run in hours to pin point the targets. You will gradually learn about the time inductive task of reading the star charts and finding the right constellation and other celestial bodies present in the night sky. It is also a great way to experience the marvels of the nature and the magical stars and bodies of the night sky.

Compare, Read reviews and Watch Videos

In order to find the best telescopes for beginners, you can invest your time in reading the reviews of the telescopes on the internet. Reviews offers a great way to understand all the features, specification, advantages along with the limitation of the various telescopes present in the market. A video review offers a huge opportunity to see the telescope in action and understand how to use the device exactly. Videos will even tell you about various tips and tricks to increase the functionality or to get more out of any telescope. Don’t forget to compare prices on the online and offline stores in order to get the best deal on your favored telescope.
