Thanks folks yep it’s been tough lately but honestly it was a really enjoyable night even with the cloud. And yes, I’ve noticed before that sometimes high cloud is accompanied by really good seeing - and especially for a visual session on bright targets it really doesn’t hurt. Regarding Jupiter & Saturn I’ve found it can really help increase contrast for some reason, probably due to reduced bright reflections in the scope perhaps?

Dennis- the IR850 certainly increases exposure times but it’s still manageable. I was at gains of 300-400 and exposures 5-10ms depending on surface brightness of the area I was imaging. Most captures were approx 3-5min and I took 20% of the best in the stack.
