Hi,
Ah, OK.
all I would suggest is that if you have any issues, capture a few frames of both dark and light (5 of each would be enough I think) to a separate folder so we can investigate on clean data.
cheers,
Robin

Re: Live stacking issues with Optolong LPro filter
OK, the next time I am out, I will capture some new light and dark frames. Unfortunately the current forecast does not have any clear nights in the near future.
I was out last night and noticed two things.
1 - At the start of the night the red curve was fine. But as the night got darker, the curve got worse. Eventually being as bad as originally posted. This happened all at 300 gain.
2 - When the red curve was bad, I decided to try the new "Background subtraction" feature. I set it to "Simple Offset" and the red curve was now good.
Not sure if these two pieces of info help or not.
Thanks,
Cey

Re: Live stacking issues with Optolong LPro filter
Hi,
sounds like you lost the red as the night got darker or perhaps clearer. Activating background subtraction will move all the curves to a similar position, but using that as a basis for colour balance is going to give rather arbitrary results.
Overall I don't think there is anything 'bad' about the low red value - it is what it is, a very weak signal. It's just that when there is practically no signal in a channel the standard AWB algorithm is not able to do a sensible job.
