You can image planets with just about anything but focal length and aperture, focal ratio play a bit part together with atmospheric conditions
I’ve produced some of best planetary images on my 6” f6 newt a DSLR and 5 x Powermate
Here’s some relevant info I put together to work our focal ratio for my current rigs
Focal Ratio for Lunar and Planetary Imaging
General rule of thumb to determine the best focal ratio of your image train for Lunar and Planetary imaging is -
Average night of seeing 5 x pixel size of your camera
Good night of seeing 7 x pixel size of your camera
Canon 600D pixel size is 4.3 uM
Average seeing 4.3 x 5 = 21.5
So focal ratio F21.5
Good seeing 4.3 x 7 = 30.1
So focal ratio F30.1
6”f6 Bintel scope use 4 x or 5 x powermate
8”f5 Bintel scope 4 x or 5 x powermate
Also some images taken last year with both 6” and 8” scopes
I don’t use filters, and these were imaged under Bortle 8 light polluted inner suburban skies
Recommend 2 programs, Autostakkert 3 for stacking and Registax 6 for sharpening and colour
Cheers
