I am thinking about buying a black-and-white planetary camera to use on my university's telescopes. I will mainly use a 300mmF20 refractor (a historical refrator) and perhaps from time to time on an 8 inch F10 Meade Schmidt Cassegrain one.
It turns out that with either of these two cameras the imaging resolution is a bit below 1 arcsecond per pixel on the 300mmF20. Would this be oversampling and cause a problem for planetary cameras?
Which of these 2 cameras would you recommend? I am now a bit inclined towards the 178M as it's larger so easier to find targets and would be better if I want to do some lunar surface photography. But I heard the 290M is a very classic and good planetary camera, and ZWO has given it a higher score for planetary imaging, what are some advantages of that? 290M has higher frame rate, but would that matter? I can just shoot a bit longer for the same number of frames on the 178M?
Many thanks for any insight!
