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.
Sorry for a a double entry in one day but I have these strange artifacts around Alnitak in SII and OIII. It appears that they are there in the single subs as well. Just very faint. Is there a way to perhaps get rid of this or address it in some way or another? Any suggestion will be appreciated.
Also checked Ha and it is there as well but not as bad
Hi Johan @lanties,
I think you mean the strange squarish diffraction pattern in Alnitak ?
This is, unfortunately, a known problem of the ZWO asi 1600 camera. This occurs due to the specific sensor glass in front of the sensor that is used, it causes reflections. I have the camera myself and I have this as well. I see it on bright stars with long exposures clearly 😐
Besides that, the data looks great 😋

Hi Mabula @mabula-haverkamp-administrator,
Thank you for the info and for the compliment on my data.
I already had to throw a full set of ZWO filters away due to terrible halo's and replaced those with Astrodon filters. The expensive learning curve of being very new in this hobby. At least the problem is only with very bright stars.
Regards
Johan
Hi Johan @lanties ,
Yes, this can be a nasty hobby in that sense 😉 ...
Unfortunately the asi1600mm has no good coatings on the mentioned glass in front of the sensor, giving you the square diffraction patterns. I have the first version of the as1600, you too? I don't know if this issue is fixed in the latest asi1600 version. (the PRO one).
Cheers,
Mabula
I Mabula, @mabula-haverkamp-administrator,
I received mine and less than a month later they released the pro version. No offer to swap out or upgrade even at a fee. You can understand there is a bit of frustration here.
The pro version, as far as I know, does not address this problem. A good friend of mine, here in Cape Town, also have the MM as well as the MC 1600 pro and he has the same diffraction patters with both cameras. His new ZWO filters seems to be better than the ones I had. The diffraction is however more prominent using the ZWO filters than the Astrodon filters. There seems to be no halos with the new ZWO filters.

Hi @lanties,
Okay, thank you for that information. I was a bit frustrated as well ;-( . I bought the asi-1600 and was a bit disappointed I must admit. The camera is great on everything but bright stars is my conclusion.
Filter can have a big influence as well, that's clear. I was using Baader LRGB filters with the camera, perhaps they were a bad match as well...
