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.
hi,
in august I wrote with mabula about this, but he has been quite busy since, having >10.000* customers to attend. I thought I had this solved today with beta6, but still I have these strange vortexes a bit.
so, this is what is had in august:
overview of panels:
milkyway moscaic done with 40mm with a Nikon D810A in Namibia,
panels 1 - 9 perpendicular to milkyway, the rest (10 to 19) parallel. each 1 hour exposure.
the above was easily done with ptgui pro, of course no stacking.
when using APP in august, I used calibrated projection with equitangular panels and a specific reference frame,
when u look at the other projections with ptgui one can gues why:
so: when using all panels i did not get good results with APP:
vortexes, swirls...
today with beta6 things are better, except in the area around the fighting dragons of ara:
similar, but a lot weaker that I first missed them
I uploaded about 8 GB in august, could still be there: maybe "StefanLenz-WideFieldMosaic" called
by the way, with quite some efford I could do this with ptgui, pixinsight, lightroom etc back in august:
APP did this with LP correction only, today:
without further enhancements. but with vortexes (used LNC 4th degree, 4 it, MBB 30%)
any ideas how to get rid of these swirls without ditching half of the data?
regards
stefan
for better understanding maybe, here a 100% comparison of the PTGUI mosaic and today's result with APP, both using all panels:
the effect gets weaker outside this region, but is is the same effect I had stronger in august no matter what I tried with APP
I admit this is hard. It must have something to to with the correction of lens distortion, at least that seems reasonable. It is quite time consuming trying around and from my findings not even consistent. Once it worked with triangles, then not for example. Integer scaled to 0.1 looked ok, scaled to 1.0 really bad. Quite irritating. I will find some time soon I hope to get more systematic in it. Not sure if this helps
This time it worked with settings:
Starcount 1000 (before 1600)
Pentagon 1 to 10 (before to 15)
calibrated projective, same ref. frame, equitang. projection
Why I just cannot tell...
Apologies for the lack of respons elgol, we did notify Mabula, but he's very occupied with some nice advances in the calibration process for the next release. Is it now working consistently?

I would not say consistantly, since it took months to find out with of course a lot of breaks and I do not know how or why - just that you need to carefully try out the crucial parameters that seem sensitive, which of course I did not know before.
What to derive from this of course Mabula suits best. Thanks for responding
so, to see some "results" and not only problems, I will show version 8 of iteration 3:
never really satisfied, too many parameters, but that is ok and always the case. wider field mosaics where you want to see dust as well are hard. Iteration 1 was done in July with PTGUI, but with 32bit fits there is more possible, but not really easier.
(At some edges I had to fill in some stars...)
best is really to have a big print or a good big beamer, so then saturation and co can be adjusted better I think.
These are of course crops. I prefer 1:2 looks with these 255 megapixel mosaic
These are very nice elgol, amazing I would even say. Sorry for the troubles you had, these can be tricky still and we are working on trying to make these wide-shots easier as well.
@vincent-mod Yes it is..
here I have a comparison between "normal" processing and with strong(er) enhancements, a crop of the above mosaic:
I guess somewhere inbetween is where I want to go
and look at this:
do you recognize the pic from your website here?
Superb, I like how the nebulae are brought out in the more saturated version. Indeed, maybe the balance is slightly towards the red in that one, but I wouldn't mind putting that on a wall.
The giga picture on wall looks like what we have yes, looks amazing obviously. 🙂 Is it your site or something you found?
@vincent-mod It is the same, which Mabula used 2018 to do some tutorials here and which is on your website, the simulation from the start. I did it 2017 in Namibia, also processed it learning from Mabula. You can tell Mabula that Adam now finally will be putting it on his website astrography.com, so he promissed yesterday
