Re: New public domain software: astro-dark-frame-library-manager
This is indeed really very interesting. I just wanted to share a different thought to add here, not in anyway trying to take away from your approach though. I can't help but thinking that when I faced this issue with mismatched temperatures in dark subtraction with my DSLR, I always adopted the LENR...

Re: sticky exposure length or sticky gain/offset for sky-limited exposures?
That's scary! I once had a snail climb up all the way on my back, until I noticed something slimy on my ear and picked the mister off me with a grin. I was so fixated and immobile when observing and fine-tuning a long livestack, this guy had all the time in the world to climb me. This experience has...

Re: sticky exposure length or sticky gain/offset for sky-limited exposures?
Yes! Kids around here sometimes come up and have a look and they're all wow and curious, but it's past bedtime for most of them.. during later times I get visits from cats, bugs and the occasional raccoon.

Nope, no one has called the cops on me yet...at it again tonight, waiting for clouds to get out of the way and Robin's cloud blasting script to be written.
How's it looking up there?
Cheers

Re: sticky exposure length or sticky gain/offset for sky-limited exposures?
Managed to get 6x15m calibrated stacks constructed from 30x30s G230 O100 exposures with the HO filter. I had started at f/4 but didn't like the star shapes, so after about 40 minutes, I stopped the lens down to f/5.17 (with filter rings) and started again. Was much happier with the star shapes, but ...

Re: Smart Histogram where to point question
Thanks Robin, that does make sense (I think!) I understand that if I go with my option 2, then there will be a lot more signal in the fainitest parts of the image (because of the target's presence) and the snr analysis won't be as accurate as option 1 (the normal way of doing it). Hope I'm understan...
