I have a very odd glitch in DeepSkyStacker 3.2: the software stop to detect any stars in OIII images and. accordingly, does not stack them together. It also does not register Ha and OIII images. What is wrong? Any ideas and suggestions, friends? 
Uwe Deutermann:Thanks, Uwe. Interesting fact - for Ha and OIII this number could be different, hard to understand
Yep, find the right setting in percentage and it should be fine. Too many stars is as well not good for stacking.
Scott:Great thanks, Scott, tried the new version - MUCH faster and bugs-free
DSS 3.2 is ancient as there have been several upgrades since then. 4.2.2 is the new standard, is 64 bit, supported and is blazingly fast.http://deepskystacker.free.fr/english/index.html
