Imaging Mars and Saturn - how long to record?
I'm wondering what is the opinion on how long to record video for each channel when using a mono camera and LRGB filters, for Mars and Saturn right now.
Obviously, the longer the better for noise reduction, but too long and you'd need to de-rotate before combining the channels.
At the moment I'm using 2 minutes each R, G, B at 30fps on Mars. Could I go longer? I get onion rings if I do 60 fps with the DMK21AU04.
On Saturn, I'm doing L for 2 mins at 30fps and R, G, B each for 2 mins at 15 fps (can't get enough light through the C11 to do 15 fps with filters).
Suggestions?
