I bought my first telescope, SW 150pds about 6 months ago with the purpose of astroimaging "when i feel ready". So far ive used my Nikon D810 for that, and I'm now planning on taking the step buying my first AP camera.
My targets would be DSO's, and not planetary. I want a mono-camera, not color.
I want to get away with a very good camera to a reasonable price (wouldn't we all...) and in this regard I've been drooling on the ZWO ASI 1600MM Mono for some time. The price for it is in the upper part of my budget, but I'm willing to if its worth it. I've seen from other treads that sensor-size isn't everything, and dynamic range and gain and all is just as important, but i have trouble understanding it all 100% when it's all new to me, but in my experience i am a practical person who learns things much better and faster with the gear in my hand. So without getting to technical, and staying as objective as possible - please help me with;
1. Is this a good camera to go for?
2. It's sold with options of filters 1.25", 31mm or 36mm - Why these options, and what determines what i would choose?
3. Would you go for another camera in this price range, and why? - Or to rephrase it a bit; If you were in my shoes, which camera would you og for?
I'd appreciate any help:)
I might add, that i understand that with my lack of experience, buying a mono-camera with filters and all might seem premature, but for some strange reason. I enjoy these "way over my head"-projects and figuring out things as time goes - I just need some guiding in the right direction.
I'm trying to figure out the cause of these weird star shapes I'm getting with my 130pds. I had them before, but someone narrowed it down to being pinched optics. So I loosened the primary retention clips, which seemed to fix the problem. Now that I've been able to get back out for another night of imaging, they seem to be back again! I made sure that the primary retention clips are still loose - should they be touching the mirror or not? I've also made sure that the primary collimation locking screws aren't done up too tight as well. Collimation through my cheshire looks to be spot on to me. Here's my image of Andromeda with the odd stars in question:
