Nikon D750, 780 or 850

[poider (Peter)]

Gudday all, I am thinking of upgrading from my Nikon D7200 crop sensor to a full frame camera, would you recommend the D750, D780 or the D850?
For astrophotography with several different lenses and also a 150 mm reflector and 100 mm refractor

If it's to be Nikon, then you may also wish to consider their mirrorless alternatives, the Z6 and Z7 possibly with lens adapter. If you'd like to dip your toe in fullframe without spending a few thousand, you could also try the D600, D610 and D800, D810, which are excellent, low noise, high res, although lacking 4K video which you may have some use for.

The D850, not that I'd recommend it just for one feature, has a very useful feature for astrophotography/low light: Illuminated buttons. No more fumbling around in the dark with a torch or phone to illuminate the buttons.

If you're buying new I'd recommend mirrorless. You can fit a 2" filter holder between the camera and scope and avoid vignetting from the clip in filter frame. You also avoid vignetting from the mirror box of the DSLR.

If Nikon mirrorless then the Z6 is the better over the Z7.

D750 has a good reputation. D780 is new so not sure if they are monkeying with RAWs or not. Some Nikon models do much like Sony's star eater. Fuji also does some star eater filtering as in XT2,3 and their GFX 50R.

Canon may be a tad noisier but if you are stacking that goes away. No RAW filtering in Canon's yet.

Nikon uses Sony sensors most often so they are often higher sensitivity but poorer Ha response. Nikon noise grain is much nicer than Sony's wormy noise and colour speckle in shadows.

Some Sony models can have a bit of amp glow in the corner. Nikon LENR (long exposure noise reduction) does not work well.
