![]() ![]() A Detailed Look at 5 Best Astrophotography Telescopes for Beginnersįirst of all - I'm not a worldwide-recognizable astrophotographer with many Astronomy Picture of the Day (APOD) awards on my shelf.Comparison Table of 5 Best Astrophotography Telescopes for Beginners in 2021.Astrophotography Telescope for a Beginner Deep-Sky Imager - Most Important Factors.Welcome to my Ultimate Guide to Choosing your First Telescope for Astrophotography. Refractors? Reflectors? What about the size? And what the hell 'aperture' and 'F-stop' mean? I want to buy a decent scope to start astrophotography in my backyard and not ruin my budget on the way! If you want to take sharp and colorful pictures of nebulae, galaxies, and star clusters in the comfort of your backyard with your DSLR or mirrorless camera, you are in the right place. When you go shopping, you will quickly find out that stores offer telescopes in many different forms. Too big to haul up onto the mount every night so I’m recommending the C11 which is much lighter and therefore easier to use and will work on an EQ6-R PRO mount.Choosing a beginner astrophotography telescope is not easy for a newcomer to the hobby. I’ve got it until January but unfortunately my mount has been delayed so I haven’t been able to use it for anything other than planetary yet. I was so impressed I went and hired one (see oops… I’ve got a C14). It really is the best all round telescope on the market. ![]() You can also stick a hyperstar lens on the front for widefield imaging. One of the best members of Big Amateur Telescope Mr Crazy physicist has been lucky imaging with his C14 edge HD with spectacular results. ![]() Apparently spherical chromatisim is what stitches up achromatic scopes more than the colour fringing and its what held back my skywatcher st80 in my robots vs nerds video! Anyways Es says the upgraded Edge HD SCT which was released in 2010 solves this problem by employing some lenses in front of the focuser which results in an “virtually apochromatic telescope over a full frame” which is “really very nice indeed”. Schmidt-Cassegrain telescope SC 279/2800 EdgeHD 1100 OTAĪccording to Es Ried the original SCT suffered from an aberration called spherical chromatism – especially in the blues. Also note that GSO scopes are ‘rebadged’ according to who is selling them. For this 10 incher you will need to be using an EQ6-R PRO mount or similar to get the most out of this scope. All in all a great value telescope for deep space astrophotography. ![]() Also worth noting that the large central obstruction in this telescope design makes them not that good at planetary astrophotography. If you happen to be using an APC sized sensor of smaller you probably won’t need to invest in a reducer/corrector lens although if you are using a small pixeled camera then bringing down your focal ratio is a good idea). To get the most out of RC scopes you are well advised to make use of its coma free optics by shooting with a large sensor camera (preferably a camera with big pixels but small pixels are ok if the read noise is small). They are mechanically good enough to do the job and therefore they fully realise the power of the RC telescope design. According to Es Reid the latest GSO RC scopes have now solved these issues. This has lead to numerous complaints on the Astro forums and social media. So you’d think that these telescopes would be the goto telescope for all astrophotographers… but for years amateur RC scopes have been a real pain in the behind to collimate. And of course being as the design is built on mirrors rather than lenses colour fringing is not a problem. The reason is this design eliminates the big aberration which hampers most reflecting telescopes: coma. The Ritchey-Chrétien Telescope design is used by all the big observatory telecopes, including Keck and the Hubble Space Telescope. 10″ f/8 M-LRS Ritchey-Chrétien Telescope OTA £2.5k ![]()
