Saturn (1st attempt) & Jupiter (2nd attempts)

Hello,

After a first attempt at Jupiter & @Nik271 suggestions to match focal ratio & pixel sizes a bit better, I tried again with a little 290MM on the f10 7" MakCass.

Both with & without a 2.5x PM.  Filter wheel problems meant I had to stick to mono (which was fine, this was just to get a sense of focus, image capture etc).

Not prime focus which probably means a little loss of contrast, and I'd left a Baader contrast booster filter on the end of the diagonal.

Saturn is v low & was almost gone so only 1 capture made.  More time spent w Jupiter - it's amazing how much rotation there is, even in 3 minutes.

EDIT: The 2.5x PM images are, to me, the worst - not sure if the focus needs to be even more precise at that magnification, or whether its a mismatch between f/10x2.5 & 2.9um pixels - ie 8x - and hence much better at just straight f/10 to 2.9um or about 3.3x ratio?

No prizes will be won 😂

Cheers
