Friday night was the first opportunity I’ve had to take some pictures of this. Thursday night was also clear but I was busy imaging comet Garradd again, this time passing close to the Coathanger cluster.
Using the club’s ATIK on the 20″ we took 41 30 second exposures binned 3×3 and also 3 each of red, green and blue binned 6×6. This really wasn’t enough colour frames and after a lot of effort I gave up trying to get a colour image and just stacked the luminance frames.
Sn2011fe is a type 1a supernova a mere 21 million light years away.
