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.
I got a thumbs up from a respected friend on this topic. I'd like to run this by Mabula before investing in a new project:
I am planning on imaging in HaLRGB for the first time. I have a CMOS camera and normally use Gain 200 for LRGB since it gives me low read noise and great dynamic range to avoid saturation of the brightest stars. The only drawback is a moderate amount of quantization at 1.74 e-/ADU. But when I make monochrome-only images in narrowband I double the gain to 0.89 e-/ADU to give me unity gain allowing for the effects of quantum efficiency.
My question is: "Can I mix gains like this?"
Thanks you,
Brian
Hi Brain @oopfan,
Sure, no problem 😉
But since you use a CMOS camera, you might have some amp-glow on the longer exposures, right?
I would advise you to make matching calibration frames for the different gain values. APP will automatically match the lights with the correct masters based on the gain values.
Mixing gain values should not be a problem, just realize that with different gain values, you need to create more calibration frames to do it properly 😉
Let me know if this is clear,
Kind regards,
Mabula
Yes, very familiar with calibration frames. So, no other concerns? Multipliers, etc. I find that APP runs well with default settings. I was just wondering if mixing gains meant that defaults no longer apply to one degree or another.

Hi @oopfan,
No 😉 not really, just take care of providing APP the necessary calibration frames.
The defaults should still give a very good result. A setting which you probably can adjust to improve things is using multiply-scale in 5) normalize ;-), that should help with improving data normalization.
Let me know how things work out with your new project 😉
