Astrophotography has been one of my favorite types of photography over the years and I am always excited to help someone new to the art get great shots right from the beginning. And other than getting a great camera and lens, the most important investment you will make is in your telescope. In this article you will find the absolute best telescope you need to get great photographs every time.

What to Look for in a Great Astrophotography Telescope
There are hundreds of telescope brands on the market today and if you’re looking for one specifically for astrophotography, you certainly have a lot of them to choose from. Nevertheless, the task doesn’t have to be complicated or even time-consuming, especially if you already know what features to concentrate on.
When it comes to the right telescope, a lot will depend on what you hope to accomplish with it. While some of the terms below may sound a little confusing to you, here’s a very basic and simple description of each of them:
- Apochromatic lenses. These focus on green, blue, and red wavelengths at the same time and therefore eliminate the blurring of color around stars and planets that you sometimes get with other types of lenses.
- Doublet or triplet refractor lenses. Refractor telescopes often use either two or three layers of glass for the lenses. While these tend to be heavier and more expensive, they will result in higher-quality images and less blurring around the images you are photographing.
- ED lenses. These lenses are made with extra-low dispersion glass that results in a lower spread of the colored light, which also eliminates that blurring of color around the planets that astrophotography buffs consider so annoying.
- Focal length and focal ratio. The focal length determines how wide your field of view is and the magnification number while the focal ratio is the actual “speed” of the telescope, which is described as f-stops. The lower the number, the faster the telescope is. F/9 or higher is the slowest speed while f/4 or lower is the fastest speed.
- Aperture. This determines how much light is let in and what you can do with it. Keep in mind that you need both a large aperture number and excellent optics to get a clear image when you look up to the sky. A large aperture alone won’t produce the same great effects.
The Three Basic Types of Astrophotography Telescopes
While these things are good to know, you should also know that there are three basic types of telescopes and they are described as follows:
- Refracting telescopes, which are the favorite types among many astronomers, have long tubes with a large lens in the front and an eyepiece in the back. They provide high-contrast images, usually come with high magnification, and are very rugged and well built.
- Reflecting telescopes use a mirror to focus and gather its light. They show you a correct-reading image instead of a mirror image and the Newtonian telescope is a perfect example of these.
- Catadioptric telescopes, also called compound telescopes, combine qualities from both refracting and reflecting telescopes so that you get the best of both worlds.
Of course, getting the right telescope means deciding which features you need for the type of work you’ll be doing because each feature is important when that’s what you’re looking for. If you’d like to know a little more about some of the best astrophotography telescopes on the market, below are a few of them to consider during your research.
