could you help me in choosing a used full frame DSLR that I could use for less than "white cleanroom" (and maybe also a bit rough) situations ?
I stick to mono CCD: I still use "old" SBIG ST8 and 10 on SCTs, and ST 8300 on shorter focal lenght otas.
I am collecting specs, tests and reviews: I am up-to-date about advancements in optoelectronics, but I have been far from DSLR photography for years and I know little of commercial items, and surely suggestions from actual astro imagers would be of great help.
I would a full frame camera that should match well my short flat field refractor.
Together with a lightweight mount this set would be a compact and lightweight one, ready for observing and for imaging while traveling (without the need for a PC and needing a minimum in power consumption terms).
The ota and the camera could stay in a backpack, so I could bring such a small, but complete, set also when travelling by motorcycle.
More: I would use the camera for ordinary photography, during public outreach activities and also as a live-view camera when I am tinkering in my small optical lab.
I consider this camera as a good compromise for observing and imaging with a minimal setup in -maybe- rough conditions, in places and at times in which, otherwise, I would just stay looking the sky by naked eye (and grumbling): it happened just too many times...
For this my idea is to get a used unit (paying around 700- 1000), renouncing to the CCD prerogatives, but at least trying to make the most of the large fullframe sensor for wide field imaging under dark(er) skies.
Resuming and briefly:
I like new compact and light mirrorless cameras, but (for the above reasons and considering that Nikon and Canon provide a well known platform with available softwares and mods/parts, plus a large and consolidate users community) at now I am considering cameras like the Nikon D800.
Is mine a good choise ?
Are there alternatives that you would suggest me as a better choise ?
I thank you.
