Normally, what exposure time (example: 1/30 sec, 1/50 sec, etc)  do you use on each planet?

I will use iCap with NexImage 5 on a NexStar 6SE.

Thanks Alex.

 

I used a Canon 600D/T3i. I captured LiveView at ~9 fps with AstroDSLR 1.3. The Jupiter is 3×1024 frames (derotated); the Saturn is ~1250 frames

 

Note that you can only stack ~3 minutes on Jupiter and ~6 minutes on Saturn before each planet's rotation starts to smudge details in the stack.

 

Cheers,

Mars is getting "bigger" and I cannot wait to try to see what I can get.

What max recording time do you recommend (for Mars) before having problems with the planet rotation?

It's a lot slower—1 turn per 24 hours, so about half as fast as Jupiter. Based on my 2018 results, I'd probably go with 6 minutes.
