I just downloaded your script and tried it out. I'm trying to get it to take 30 second exposures about 5 seconds apart for a star movement time lapse. Which settings do I set in the script menu once I load the script? Do I also need to set the override Tv to long exposures in enhanced photo settings? Where in the script menu do I set the # of seconds?

You should set shutter speed in the script menu.Set Tv to 32 (or Tv to 0 and Tv + sec to 30 if you want exactly 30)Set the interval to something like 350 (30 sec exposure, 5 sections in between). If you are shooting raw, saving / processing time may be close to 5 sec.If you want 5 sec between exposures, you'll need to turn "Disable Canon Dark frame on", otherwise a 30 sec exposure will take 60+ seconds.
Thanks, I didn't see your reply before I edited my OP. As I write this I've got it shooting the stars at 32 second exposures - it took me awhile to figure out that I needed to set the Canon setting to continuous as well, before I did that I was getting one long exposure, then all exposures after that were short. Once I set the continuous on and checked it in the script menu it seemed to work ok.
I tried it a couple of times and I could not get it to do continuous long exposures until I set the canon setting. Perhaps it's unique to the A495? I have a couple of A490's too I can try it in. I'm using 1.4.1-4319 CHDK.
I just made a short movie from the short session I did, I'm getting a lot of amp glow from this camera, so I may experiment with the dark frame settings some more, and I'm also just shooting jpg in this trial.
Also attached the short timelapse I just did - looking forward to doing some more when I get more time - it's late now and I'm calling it a night for now.
Thanks - I may look at getting a better model that'll take CHDK at some point - I picked up the A490 and A495 because they were dirt cheap, have no IS and work great for aerial photography, especially on multirotors. I just thought I'd try them for night time lapses since I already have the CHDK with them.
I'll try it with dark frames enabled - but unless I'm mistaken, aren't dark frames more for use with long exposures stacked for one clear image, not so much with time lapses?
When you say the bug you found made it ignore the interval - exactly how?
And on your D10 it doesn't matter what you set the continuous option (on Canon firmware) to it will still take continuous long exposures?
