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.

1st time trying APP Mosaic; running into some big issues

Yesterday I tried making a mosaic of 2 sets of images.  I was happy initially to see that the integration worked.  This changed when I looked at the stars which had a strange whirling pattern.

I submitted my project using the settings recommended in the video on the APP site, (I believe by Sarah Wagner) but it is possible that I missed something.

After this I looked on the forum here and could see that others ran into this same general issue.

Wouter had a set of setting recommendations that I went back to and applied to my project.

The project became overwhelming all of a sudden.  It ran overnight on my 2018 MacBook Pro and still is only 10% through the Registration phase.

Might there be something wrong that I am doing?  I would ultimately like to stitch perhaps 6 to 8 images together but this wouldn't be viable.

I will wait perhaps an entire day until this finishes, but I am wondering whether there might be a better way?

@paul-from-northern-mi Hi Paul,

How many frames do you have per panel? If there are a lot then APP will try to register each of them, which takes a LONG time. In such cases you may be better off processing the individual panels first and then combining the integrated panels into a mosaic.

Yes, I may have to consider this.

I have 200 frames being processed right now.

Would there be a drop off of quality by doing separate processing and integrating in a separate project?  Would this be done same method as before or could you drop the need for a calibration sequence?

@paul-from-northern-mi Once the panels have been integrated, you can load them as lights without calibration files. There may be a slight drop in quality but it will be minimal and barely noticeable if at all.

Just out of curiosity; should a set of 200 images result in likely over 2 days of processing?  Presently it is at 3000 out of 21,000 registration tasks.

@paul-from-northern-mi That depends on the registration settings. When using 500 stars, it should be much faster than that. When using 2500 stars or more it may take that long. That's why I advised to split up the processing and process the individual panels first to registration goes much faster.

Yes, combining 2 already processed images in a dedicated mosaic file did a lot better than putting everything together with the processing.  I couldn't even see the seams or difference in brightness.

I am a glutton for punishment but I would like to try adding more tiles to make a more expansive mosaic.

Thank you!

Paul
