UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Before I release it, I will make sure that everything is working properly and then I will release it.
While taking frames of the recent M100/Ceres conjunction, I found a good LRGB formula to use. Unfortunately as I worked with my frames, I discovered some of the subframes were slightly occluded by high clouds. This caused their color balance to be slightly off even if I used the same formula on every set. I color matched the combined LRGBs as best as I could, but it would be nice if there was a batch tool to do that.
One option could be to automatically choose the reference frame as the one with the least RMS value from the average of all frames, or let the user choose their preferred reference frame.
Then the tool would automatically compare the light parts of the frame above a user-silder for background cutoff, and try to automatically adjust the LRGB for each frame to match the reference frame.
I know it wouldn't be able to fix the light lost, but at least the frames would be similarly tinted and not vary red/green/blue with each set.
Thanks for a great tool.
