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.
Hello hello everyone,
it would be boring, if there would be no issues or something else with this camera, especially with calibration etc.
A few session go it was everything fine, but now it cames back it seems.
I do everything exactly the same in every single session, also calibration frames. The only thing that changed was that I updated my AsiAir Pro a few days ago. Nothing other changed.
I do every Session at the end flats and dark flats with the same temperature and gain, the flats and darkflats also with the same exposure time and same gain and temperature as my lights.
My AisAir is runnign with the ZWO 12V adapter over my power tank and the 294 mc pro is running at the 12v output at the AsiAir.
Since two sessions/nights at M31 Narrowband I i have some calibration issues. The ampglow in thr right upper corner didn´t calibrate out fully, also the amglow in the lower right corner.
Like i said, I have do ALL things like every other session in the past and there was no such a issue.
What´s wrong here? I stack it in DSS, APP and AsiDeepStack but its the same issue in all this stacking programs.
I do last night test-based three flat sessions with 28k avg, 30k avg and 32k avg but the issue is the same.
Is it maybe the dark flats oder darks? Because of the banding?
In my 300 seconds light exposure in the asiair in preview is no banding.
Hope anybody can help me.
Best regards
Tobias
Hi Tobias, when I look at the histogram of the Masterdark and Dark Flat, I would say that the Dark Flat has an extremely high average value. That looks like a light leak.
Which then messes up the calibration and leaves amp glow residue in the image.
Regards.
@minusman Hm, you are right.... and at the bottom of the Masterdarkflat it looks like a bright stripe. Curious....
Maybe it was my head torch. When I let capture the darkflats I dismantle all the things that I don't use any longer and for this I turn on the head troch with the white and bright light....
Last night I shoot IC 1805 and after 4 hours integration time I have a similar issue. 😪 😪 😪 😪
ISSUE SOLVED
Guys, I made it. The ampglow now is completely gone. 
You all was right about the darks. The darks were he issue all the time.
And now I know about what you guys mean with the same temperature as the lights. The ambient tmperature. Thought alle the time -10° is -10° and works for all frames. But then I took my camera out to a clear night and put it on my scope and shoot the darks as close as possible at the ambient temperature as my lights from IC 1805.....and here it is, it was the key and works 100%!
Sorry for all the posts I put in here with my issue and sorry to annoy you all with that.
Cheers and Clear Skies!
