Hello everybody. I am trying to decide between the Askar 50P and the SV535 for a wide-field setup with an ASI585MC camera. Both seem very interesting, but each has significant pros and cons.
Askar 50P Pros: built-in 360° rotator, dedicated autofocus kit available, enough backfocus, easier filter integration, and overall, it seems like a more complete astrograph ecosystem. Cons: the spot diagrams appear noticeably worse compared to the SV535, and it is slower at f/3.8.
SV535 Pros: extremely fast at f/2.8, surprisingly good spot diagrams, and very compact/lightweight. Cons: only 24 mm backfocus, no built-in rotator, and front-mounted filters.
I mainly plan to image large nebulae, IFN, dust regions, and other wide-field broadband targets.
What are your thoughts on these two systems in real-world use? Which one would you choose and why?
Thanks in advance, and Clear Skies!
