Afternoon, everyone. As it says, I've been using an unmodified Canon T6 for a couple of years now and I've been looking at making the move to a cooled astro-cam. The biggest reason for the move is noise and dark frames. My T6 is pretty noisy, and we all know the conversation about darks with a DSLR. The idea of a darks library is pretty tempting.
All that said, I currently use an Orion ED80 with it's reducer/corrector which makes it 510mm and f/6.3. That with the T6 gives me an image scale of 1.7 arcsec/pixel. I've been looking at the ZWO ASI533 MC Pro, the ZWO ASI183 MC Pro, and the ZWO ASI294 MC Pro. All cooled OSC, I really don't feel I could handle mono/filters right now. Not just the equipment, but the processing as I'm still building skills in processing. I use NINA and PHD2, and it all rides on a Sirius mount if any of that matters.
The 533 would give me an image scale of 1.52 arcsec/pixel and has a 50k full well, but I don't know how I feel about the square sensor and the FOV it gives.
The 183 would give me .97 acrsec/pixel and only has a 15k full well. I've heard that the 183 likes faster scopes, and at 6.3 mine's not really considered fast.
The 294 would give me 1.87 arcsec/pixel and has a 63k full well which is a lot more then my DSLR is (i'm pretty sure). The pixel size and scale and FOV would be closest to what I have currently with my DSLR.
I've played around on telescopius and stellarium with the different FOV's and settings for the different cameras. I initially thought to go for the 183, but now I'm leaning towards the 294, mainly because of the full well and the FOV. Am I thinking about this all correctly? Does anyone have experience with using the ED80 (or similar) with one of these cameras? I'm not necessarily locked into ZWO products, but these seem to be more ubiquitous than some others. Any thoughts or insight is appreciated.
Also, if anyone has a book or resource that covers imaging with a cooled astro-cam I'd be interested in it as everything I've got currently revolves around DSLR imaging. (specifically I'm looking for info on working with gain, offset, and cooling.)
