mosaics from rotated camera ...

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

Ah that is nice, thanks for sharing. 🙂
