wingeing Pom 723 Report post Posted October 6 Last night's effort - another clear Moonless night. What's going on? This is 15 x 3-minute subs with the Hyperstar 4 & ASI2600MC-Pro camera on NGC7789 - the open cluster that thinks it is a globular. Very weird thing about this CMOS camera that I am having great difficulty in coming to terms with - THERE DOESN'T SEEM TO BE ANY HOT PIXELS!!!! What gives? Are they taken out somehow on-chip???

timthelder 204 Report post Posted 20 hours ago I did a quick read on the reviews of those cameras a while back. And that seemed to be the consensus, no amp glow, no darks, etc. Pretty amazing. Back in my day we had darks, flats, dark flats....Everyone is so spoiled these days! 1 Share this post Link to post Share on other sites
