I have been using a Baader-modded Canon 450d with APT for astrophotography. It has been a great first camera for this hobby but I find that this camera to be little bit outdated now.
I looked around cooled OSC astro cams with APS-C sensor like asi071 but they were a bit over my budget so I thought a more recently released DSLR would be a nice upgrade for a reasonable price for me. And I found that Nikon D5300 is a popular choice these days, just like Canon 450d in the past.
Looking at D5300, I came up with few questions:
1. I see number of modded D5300 on classifieds but they are all full-spectrum mod. I use a refractor and I read that a full-spectrum camera can bloat stars on refractors. Do people buy an additional IR/UV cut filter for refractors this case?
2. The field flattener/reducer I have has back focus of 55mm. This was reached with no problem with 450d's 44mm flange focal distance + 11mm T ring. But how do you make 55mm with D5300? Wikipedia says Nikon F mount has 46.5 mm of flange focal distance. Can you recommend me a T ring for this camera? How thick is it?
3. Will this be a noticeable upgrade? Do you rather recommend saving up for a cooled camera like asi071 for the future?
4. D5500 is available at almost the same price. Which one should I get if both are available in same price range? (I will be getting a modded one and it'll be used for astroimaging exclusively)
Thank you very much for reading the post and I will greatly appreciate any advise!
