niteclicks, thanks for the feedback. I've never stacked in my life but I imagine it's just sequential shots without tampering, assuming the tracker is doing its job and then I think DPP can do the job??
I think I may have dropped the brightness of the 24 mm a bit thinking it was overexposed.
I assume B is used for the longer exposures and I need a remote release although I've started using the 6D WiFi and that might be a solution (it is to the cold).
Can you suggest the manual settings that you might use and the time for a couple different scenarios?
What do I look for in terms of judging the quality of results, say between my lenses and focal lengths?
Can you suggest any threads or links that would be aimed at my situation as a beginner with stars?
I'm an handyman machinist and welder and am planning to modify the final attachment point of the tracker so that my mount location is up and level rather than angled at Polaris. Do you foresee any problem with placing my gimble (quite light Jobu) on that as I would place it on a tripod? I prefer gimbal to ball head (which I don't have at the moment).
Asking a lot with all these questions!
