Thanks Alan, I'm using the large Scorpion (I think you have the same one) ROI'd to 600x500 for the 30fps rate.  I'm always hoping that 16 bit will capture more nuanced detail but sounds like you feel 8 bit is more than enough. I did experiment with Jupiter at f/45 and needed to go down to 8 bit to get a decent frame rate.

Happy Thanksgiving!

Jim

Quoting Alan Friedman <alan@greatarrow.com>:

Very nice, Jim. Are you using a monochrome PGR camera in 16 bit mode? I haven't found an advantage on Jupiter to use the greater bit depth with the corresponding offset in slower frame rate, though in my 10", I can just manage 30fps in 8 bit mode with the Flea3. I sat outside a little earlier than you last night. The seeing was moderately good I think... seemed to go downhill around 2:00am local time so I went to bed.

all the best,

Alan
