I have the option of locally sourcing a used Orion 8” astrograph. The scope comes barebones: no coma corrector or collimator. I’m hoping to get into DSO imaging with it and plan on using an ASI183 camera so, should I worry about coma on such small sensor (compared to APS-C or full frame)? Is there any way I could simulate the appearance on an image?
Maybe I should’ve started with this question but, is this scope a good option for starting in AP? It’ll be riding on a losmandy gm811 mount so that “should” be no problem. My reasoning was, it’s about the same price as a good 80mm refractor but, much faster and with a bit longer reach for smaller objects. That is, as long as I don’t need to account for a coma corrector
So, thoughts on this?
