I'm trying out APP. Calibrated my frames. Hit <analyse stars> and the program gets part way through my stack of calibrated frames then the Console goes black and APP just hangs and stops activity. Has happened 4 times now. I tried upping the memory to 8gb and it got to 37 of 38 frames then hung again. Any idea what's going on?

Increasing the memory seemed to help. Didn't realize you have to restart to update memory setting. Have gotten through to integration now without problems.

I have a problem when i load ha, oiii, sii data and i get to analyse stars it always reports oiii as failed but processes ha, and sii without any problems at all. Running a mac pro with 64 g of memory, if i run the stack thru pixinsight and then put the single image with the group it is the only way to continue. Any help

Dear Alan @alanrichards106,

Thank you very much for reporting your issue. I just finished extensive work on a greatly improved Star Analysis module for the next release APP 1.076.

BIG IMPROVEMENT, STAR ANALYSIS, extensive work has been done on improving star detection and analysis, due to some users reporting issues with Star Analysis in APP 1,075 (  https://www.astropixelprocessor.com/community/rfcs-request-for-changes/problem-with-star-analysis-1-075/ ).  I am happy to announce that all reported data that gave issues, now works flawlessly. The Star Analysis module is also twice as fast now while becoming much more robust and memory consumption is kept very low as well. Users will notice that APP will detect more stars on more datasets as well. Here are some performance graphs that show Star Analysis of 100 H-alpha frames of 5 different optical setups, for 4 CPU threads, 8 CPU threads and 16 CPU threads, APP 1.075 versus APP 1.076:

StarAnalysis behaviour 4 CPU threads
StarAnalysis behaviour 8 CPU threads
StarAnalysis behaviour 16 CPU threads

If you want, I will test your data as well to make sure this works propery on your data as well. If so, can you upload it here:

Please create a folder with your name and let me know once uploaded, I will have a look as soon as possible then.

I will try to release a beta with the improvements as soon as possible 😉
