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'm facing some calibration issues that I just don't understand. This was first light for me with this camera. I'm binning 2x2 when capturing as I don't need full sized images and want to save disk space.

Here's what I shot:

Lights HA 120s Gain 100 offset 50 Bin2x2

Darks 120s Gain 100 offset 50 Bin2x2

Bias .2s Gain 100 offset 50 Bin2x2

Flats HA 25k 1.39s ADU Gain 100 offset 50 Bin2x2

FlatDarks HA1.39s ADU Gain 100 offset 50 Bin2x2

 

This is my calibrated result every time. I've tried with bias, and flat darks, and both. I've tried flat ADU values ranging from 2k to 25k resulting in no difference. I've processed with Astro Pixel Processor, but also tried PixInsight with the same results. I'm wondering if the Binning has something to do with things being read incorrectly, as that's the only difference I'm seeing compared to other users.

Here's a zip of 1 frame of the above if someone can tell if there's a mismatch somehow or if binning caused the issue.

Solved! Turns out the offset on my darks did not match lights or flats. Reshooting darks fixed the issue.

Great and thanks a lot for sharing! The offset is a tricky thing I notice more often.
