starnet59 For what reason they could not go to sleep while the S50 is taking shots or mosaics? It works perfectly, I neve had a single issue with my S50, not even with the previous "startrail bug" firmware.
I start a session, set my alarm for 2-2.5 hours later, then start another session, set my alarm for another 2 hours later and so on. Recently I can take 5-6 two hours sessions a night and I sleep well. I need 3-4 nights to collect about 6-7 hours of exposure from each objects. Forget about the tripod, use a rock solid column instead. Set up and adjust S50 accurately and it will work flawlessly, frame rejection will be close to zero.
