Beta 23 can't seem to register mosaics

@imnewhere I created a mosaic with beta23 by first integrating each panel separately and then creating the mosaic from the integrated panels. Worked like a charm. 

Try increasing your star count to 2500.  I found that even with creating each master panel for the mosaic, it would not perform the registration until I increased the star count from 500 to 2500.  I was stacking a 16 panel mosaic too 😀

I have tried a few different mosaics using beta 23 and it can't seem to compete the registration task. It gets stuck at 80% and goes nowhere even if you leave it for hours. This is an example of where it is stuck at this point and has been for over 20 minutes.

 

 

Hi @imnewhere,

Thank you fo reporting this and for the attached screenshots. The screenshots illustrate the problem here partly. The mosaic calculation is not converging at all, the RMS is still above 70 pixels with so many iterations where normally it will be less then 1 pixels with less than 100 iterations. This means that the mosaic calculation is not working for some reason. Maybe the star count is too low in 3) analyse stars like Simon @stastro indicates? Or there is a problem with the data. I was able to register a 50 panel mosaic just the other day with beta23 and experienced no such problem.

So maybe it  will help if you can share how many stars you have set to detect in 3) Analyse stars and consequently, how many stars are actually detected by APP. And do make a visual check for those star counts with the star map image viewer mode. Maybe it shows that APP is locking on to noise or hotpixels instead of stars on 1 or more of the images?

To make sure nothing weird is happening, i just tested an 8 panel OIII mosaic, and it worked perfectly fine. So I think me need more info about your data and the settings in 3) and 4) that you use.

You need to increase star count (2500 recommended for mosaics) and change it from Quadrilaterals to Pentagons, that is the only way I can get my 16 panel Mosaic to be created, otherwise it sits in the same position as you are seeing it stop at

Hi @imnewhere,

Just checking if we need to help you with your mosaic still? Do you want me test your data and see if there is a problem in APP somehow?
