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. Â Before I release it, I will make sure that everything is working properly and then I will release it.
Hi,
I am having issues with a set of oiii data.
I get really strange artifacts in the illumnation profile of the stack, for a lack of better words, but only in the oiii, the H-alpha stack is smooth as butter and looks very good.
Ha:
Â
O3 with LNC:
Â
O3 Normalization map:
Â
It is quite obvious (to my eyes) that the normalization map fits very well with the problems in the image.
Â
If i turn off all LNC i get a better result:
Â
Does anyone have an idea what is going on here?
Â
The camera is a Altair Astro Hypercam 1600M and filters are Baader 1,25" filters.
The o3 is quite weak compared to the Ha.
Edit: I have inspected all flats, darkflat and lights, and I don't think there are any that sticks out as "bad".
Â
Any clues would be greatly appreciated. 🙂
Interesting, it almost seems to correlate with the bright patches in the stack without LNC.. I have no real clue, and my answer is going to get boring on this forum, but if you share some of the data I might get a better idea. 🙂 You can upload like 10 of each calibration subs + 10 OIII lights to our APP server, login/password: appuser please create a folder with your name on it first, thank you!
I figured it out. 🙂
The normalization issues were indeed a result of stacking artifacts introduced while stacking. When these were resolved by changing a few settings in registration, the problems were gone.
Excellent!
