[Solved] Mosaic Failing to Render Correctly

bump please - looking for assistance.

Hi Mark,

if I understand you correctly the single master linear integration files are ok but the mosaic integration of some of them fails?

Which version do you use? Maybe you have read about my trouble with my latest mosaic. Here only the southern panel made trouble in all color channels. The northern was ok though there is no obvious difference between them.  The problem appeared only in V2.0.0 beta 4. I could solve it by temporarily returning to a stable version. 

Cheers Pete

@pete_xl so high-level the issue is, if i stack just a single panel by itself, it works just fine. As soon as I try to stack two panels, as noted in the above scenario, it is blown out as non-linear. If i try to take it to pixinsight and stretch it, it's also blown out white. But that same panel when by itself works just fine.

I'm currently on APP 1.083.4 version which is my understanding is the latest. 

APP 1.083.3 worked fine in my case. My issue was related to APP 2.0.0 beta4 and my advice would have been to go back to the last stable version. So no idea whats on. I can offer to check your data on my system if you like and if you want to provide a downloadlink for the panel masters.

 Mabula-Admin or  Vincent-Moderator ? Anything you guys can assist with? 

We've let Mabula know, he was quite busy with beta 6, I've asked again.

Hi Peter @pete_xl,

It sounds like a data normalization issue to me. Which settings are you using in 5)Normalize ? Did you try different settings in 5)Normalize?

Do I understand correctly that the SII mosaic always fails somehow? If so, can you upload the SII mosaic panels so I can test it myself and find the cause of the problem?

Please make a folder with your name and let me know once uploaded. I will look at it as soon as possible 😉

Hi @mabula-admin, 

I've added 3 files for each panel, each filter. Everytime I try change settings, I just get more blown out panels. 

I've included a video showing all of my settings with results. When I try them as a mosaic, I get weird results. If I try it as a single panel, for example, SII panel 4 and use the flats/dark flats and dark, no issues with single panel. Only when I try doing as a mosaic. I've tried changing registration from normal to mosiac as well.

All files including video of entire setup found in: Mark Carter - Mosaic Failing to Render Correctly

Thanks

Hi Mark @endeavor384,

Thanks for the upload, I will look at it soon. Just 1 question for now: why did you not prepare the mosaic panels first before creating the mosaic? That is the recommended workflow, because it is faster and more robust 😉 Did you try that workflow or are you always trying to create a mosaic from all individual panels?

Hi @mabula-admin -

historically I've just put ALL lights, flats, dark flats and darks in at once and just waited for it to spit out a final mosaic. 

I had issues doing 1 panel at a time, until I had all panels completed, and then tried doing the mosaic. Issues from horrible/unremovable gradients to overlap lines that can't be easily removed, to mismatched stars. I found more luck with doing them all at once but lately, hasn't been the case. I can go ahead and try doing each panel individually but again, just historically I had better results in the past doing all at once. I also have a very fast gaming PC so doing this full mosaic wouldn't take me much more than an hour or maybe slightly over to press integrate and just let it run.

Hi Mark @endeavor384,

Thank you very much for reporting this issue. After testing I can fully confirm that you encountered a serious bug relating to both the adaptive pedestal and data normalization. I will make sure that it is properly fixed in the next version 😉 I am working on it right now.

Hi Mark @endeavor384 & @pete_xl & @vincent-mod,

This issue is fixed for 2.0.0-beta7, it gives these results now with advanced normalization + MBB 10% + LNC1-3x for the 3 mosaics:

Thank you very much for reporting the issue 😉

Mabula

@mabula-admin Thanks Mabula! I'm actually somewhat relieved because I had issues with other mosaics that I just simply ditched the project because of this but felt I would report it when it happened this time. 

When do you relatively anticipate that version with the release fix would be made generally available?

Thank you

Mark
