It's for imaging, camera is the ASI1600MM-C, 3.8 pixel size; 4/3rd sensor (17.7mm x 13.4mm), resolution 4656 x 3520.

I could try my Nikon D5300 (APS-C) but i need deep cooling and long narrowband subs. The Nikon is not suitable.

Looking at the calculators, 320mm might be ok if i work the diagonal axis into the framing.
