Whether you are looking for a telescope to present them to your kids or your niece or nephew, or if you are looking for one for yourself, if you are new to astronomy, this will turn out to be a really hard task. There is a huge difference between gazing at a sky full of stars and thinking it is beautiful and you will like to know more about the star clusters, and actually starting to learn about them more with the help of best telescopes for astrography.

Not only are you going to need to learn more about objects in the night sky, but you also need some knowledge on how astrophotography works, which can be quite different from normal photography.

If you are looking for one for your children or your nephew or niece, you are going to need to explain at least the basics to them. If you are going to buy one for yourself, if you are a beginner, you might be at a complete loss at what kind of telescope to buy to fulfill your needs. Maybe, even if you are an expert in this field, you are still at a loss on what kind of telescope is good these days in the market.

Well, fear not, for we have a made a compilation of the 10 best telescopes for astrophotography, that you can refer to and find the one best suited for your purpose. Going along with the assumption that you are a beginner, we have also provided some tips on what you should look for while choosing your telescope. Let’s have a look, shall we?


Features to Consider While Buying the Best Telescope For Astrophotography?

Aperture has a firmer place when you are considering for visual astronomy, but with DSO photography, It’s better to take optical speed into consideration. The preference towards speed comes from the method of measuring the signal to noise ratio. DSOs are quite dim if you compare them to the scenery we see in daylight. Under the stars, the more photons we can capture, the better is the guarantee of a good picture. The number of photons captured is measured in SNR or signal to noise ratio. More photons automatically means more SNR.

Presence of more SNR means a smoother, soothing picture. Optical speed means the speed at which the photons fly into our cameras pixel’s for the whole picture to be possible. The faster it can get in, the better it is.

Faster optical speed might mean an increase in SNR but for reducing noise, other features needs to be considered. There are mainly two best ways to do it. You can either photograph under a dark sky, as in an area where light simply is not present in your surrounding or you can employ the use of a special kind of narrowband filters.

How do you understand what the speed is? Well, you can tell it by checking the focal ratio. We get the focal ratio when we divide the focal length by aperture. Speed is changed on the square of focal length. Which means, an f/4 is faster than f/8.

You are also going to need an equatorial mount for DSO photography. It aligns with the earth’s pole while Alt-Az mounts succeed in field rotation after long exposure.

The size of your telescope depends a lot on the size of the equatorial mount. In essence, the mount is the foundation of your photography system. Everything hinges on it. If your mount is good, better performance is guaranteed. Remember, the earth is essentially rotating on its axis and around the sun. You are always moving. For taking pictures of the night sky, the DSOs are fixed. An equatorial mount stabilizes the camera and focuses on the same part in space, even while the earth continues to move under it.

Whatever else you decide to downsize on, it’s better to not save on the mount. An entry level minimum size mount can cost about $700 while a really good one can be $3000.

What Kind Of Telescope Is Best Suited For Astrophotography?

The choices for telescope in astrophotography is wide and varied. You might want to take your time learning about the different types before choosing the one for you.

Refractor Telescope

DSO photographers usually recommend starting with a small refractor for beginners when choosing a telescope. A refractor is made out of a convex glass lens that helps focus the light at a position that is plane for an image. Achromatic and apochromatic, these are the two known refractors.

A convex lens is somewhat similar to a prism. It manipulates light so it can be bend to a certain focal point. Usually, when light is bent, the light typically break into different parts on the wavelength. When these different wavelengths focuses on certain points, it result in what is typically known as chromatic aberration. Telescopes usually have a special type of glass, so that the dispersion is low in them and chromatic aberration is reduced.

For achromatic telescope, there are usually two pieces of glass which helps bring the scattered light to one focal point. However, achromatic lenses only focuses on blue and red light, and leaves green light out of the equation blurry.

Due to this complication, apochromatic system is considered better. As it can hold three pieces of glasses, it can bring red, blue, and green, all three of the lights to the same point. It is better to go with apochromatic telescope for astrophotography. Of course, if your focus is narrowband imaging, since the wavelength of light is narrow here, achromatic telescope would do the job just right too.

Astrophotographers usually tend to purchase apochromatic telescope. This is because the quality of the focuser is better and is considered better quality in general.

Small refractors are recommended for beginners because it can bypass a mount’s tracking limitation, takes care of polar alignment errors, and is easier to use in general than any other kind of telescope. Small refractors also have an amazing list of targets that can captivate beginners and advanced photographers.

Objects in the sky can be way larger than any of us realize. Nebulas can cover multiple moons. Small refractors field of view is quite large and those vast expanses of stars are captured easily. The field of of view is depended upon the focal length and the sensor size.

For small refractors, you can move forward with a small or medium sized mount. Most people will usually tell you to get the best mount you can afford. However, the truth is, if you have a refractor which is light, the mount’s tolerance is far greater. Compared to a heavyweight telescopes with longer focal length, mount works just fine on lightweight ones. Magnification increases with the focal length. Your telescopes limitation are usually more exposed with better magnification. Which is why, a small refractor is a better option.

Newtonian Telescope

A newtonian telescope consists on two mirrors. One parabolic mirror directs light onto another mirror, and this light is then turned reflected on to a focuser on the telescope.

Newtonians has one more step to its set up which is known as Collimation. It is made possible by adjusting the three screws of the mirror at the back of a telescope. This step is taken so that the light falls upon smack dab at the center of the focuser and it comes in at a right angle in coordination with the sensor. Collimating a telescope is not hard but you do need to get certain amount of practice and learn the mechanism properly. You can also buy a collimation cap to make it easier. There’s also autocollimator, which helps even more with the angle.

Laser collimator, one the other hand, have some drawbacks to it. You certainly don’t need laser collimator either. Not when you can reach the adjusting screws and look down the focuser at the same time.

You are also going to need a coma collector is you decide to buy a newtonian. The further you move from a mirror’s centre, the greater is the distortion in the images. At this stage, the starts starts looking like comets, which is why it is called Coma. With the help of a coma corrector, you can fix this distortion.

The best part about Newtonian telescope is that most of them a optically fast and typically start with f/4. The not so good part about Newtonian is its size and weight. The size makes them a typical target for the wind. The mount will also have a hard time working because of the load that is added by the size and weight of a Newtonian, especially when you compare it to a refractor. In this case, you need to add more counterweights along the lines of the mount head and have to face the camera downward at the home position. These two preventive measures helps reduce the impact a Newtonian has on a mount.

A basic Newtonian can be great for beginners. Compared to refractors, they are way less expensive. Considering Refractors tends to have a change of price depending on the size and quality. A lot of people end up upgrading the focuser on a Newtonian. So, you might end up a little more than you signed up for later on but its still a good option.

Schmidt Cassegrain Telescopes

Schmidt Cassegrain Telescopes are a smash up between refractor and reflector. An SCT consists of several things. A spherical mirror that relies on a piece of glass that is curved slightly and a Schmidt corrector plate which is on the very front and it corrects the light rays so that the image can be usable. If you are planning on doing length planetary imaging, SCT’s dual role might be what you need. Usually, SCTs are a f/10 and have a .63x or 7x focal reducer accommodating them.

SCTs are of two basic types. One is the regular SCT and another is aplanatic flat-field SCT, the likes of Celestron Edge. Similar to a refractor, the image that comes out is curved. With an aplanatic SCT, the image plane is flattened out. This is even more relevant due to the increase in full frame size camera sensors. Again, much like coma, the further you move from the mirror’s centre, the worse the curving gets. If you have a small sized sensor, that is, those that are restricted to planetary image sensing, a regular SCT is enough.

For DSO photography, if you are using SCT, the recommendation is to go with an off axis guider. This way, you can destroy the difference between the guiding system and the camera. Similar to the Collimation for Newtonian, OAG will take some practice too.
