+RonC Posted January 24, 2021 Share Posted January 24, 2021 (edited) Last night I settled on M81 & 82 as they were furthest from the bright Moon. I set up and aligned as usual and framed & focused the target. I used my usual settings on the Hypercam 183c, Gain 400 and exposure of 120secs. I did 50 exposures, they looked a little dark on the APT screen but when I came to stack them on DSS only 2 frames were used and only 6 stars registered. Now were the conditions and seeing pretty bad last night after snow or do I need to alter my settings of gain and exposure and recheck my focusing?? I've never had a problem before as I usually get enough star's to register in DSS. I'm at a bit of a loss! Any suggestions or comment about last night's weather would be welcomed....

+Ibbo Posted January 24, 2021 Share Posted January 24, 2021 I am guessing the 2 that stacked were from earlier in the night. The moon and thin high cloud was doing a great job of obscuring the stars etc. and eventually the mist settled in and that was end of play.

+RonC Posted January 24, 2021 Author Share Posted January 24, 2021 Yes they were earlier subs Steve, hope it was the weather not the set up! Thanks Ron Link to comment Share on other sites More sharing options...
Neo_uk Posted January 28, 2021 Share Posted January 28, 2021 I had the same issue ... Did m42 in ha then as that went out of view had a crack at the whirlpool galaxy ...and none of the data I captured on either target was usable ... I'm guessing like Ibbo said thin cloud 😔.
