As a noob to EAA, I do wonder if starting out attempting EAA with a manual push-to dob is a good idea? You'll get stars but to get even the bright nebula's you will have to push the software (like SharpCap) with lots of knowledge on how that (to a noob) software works! Search for threads on Cloudynights from astrojedi who has proved it an be done. He has incredible knowledge concerning all camera sensor technology and lots of advance experience in Sharpcap and others. He may chime in here to help you ... because it absolutely CAN be done. But in my opinion to start out ... with no experience in EAA ... at least get a GoTo dob to start with.
A friend of mine has done heaps of EAA with a goto dob and hopefully he won't mind me sharing some of his journey from his flickr account. Just watch the images change as he learnt to use the dob and camera and MOST importantly the software Sharpcap and also Astrotoaster ... both of these he mastered with experience. He accepted the initial shots would be so-so ... but pushed on and grew with his experience. Its a great journey!
Link to photo which got him interested ... normal camera and lens lunar eclipse ...
Then came this ... a goto dob with his canon mounted on it ....
which lead to this ... https://flic.kr/p/xWWZmS and this ... https://flic.kr/p/xhEQSH and this ... https://flic.kr/p/yffoCD
which lead to a better true astro cam on the dob, and other cams on the same dob, as well as several tubes on the same dob .... and IMPORTANTLY a counterweight on a sliding rail system in order to balance the whole thing (so the ALT motor was still able to push the whole heavy weight skywards! ... https://flic.kr/p/VS8uZa
Which lead to shots like this on that dob ... lots of shots in this album link ... here's what you can do IF you push past the equipment and software learning and just keep pushing to the limit ... even on a dob! ... just masterful given its on that crazy heavy loaded dob! Just fantastic stuff .... https://flic.kr/s/aHskGspbb6
Now, years later he has only just got an EQ mount. So moral of this story of his and my post on this thread .... .............
1. be prepared for everyone to tell you every scope and camera is better ... BUT just push with what you can afford and have available to start with. Push to the limit!
2. be prepared to struggle working out what all the controls in the software do ... WE ALL DO ... EVERYONEs first shots are not the best ! LOL Just push it as hard as you can ... it teaches you something EVERY time.
3. want to throw another camera and OTA or two or three on the dob ... you'll be told to buy another mount or two or three ... push like my friend did and creatively balance with a sliding rail counterbalance system ... and learn, learn, learn.
4. Finally when you do reach the stage where you are a "guru" with your equipment ... you'll know exactly what the next equipment - mount, scope, camera and software - you need to get to. And to get lots of beaut objects and images. Then and only then (in my opinion) should you maybe worry about hooking it up to operate remotely, with rasp pi and small intel repeaters and platesolving and autoguiding and ..... etc
