I managed to get out for an hour. Earlier in the day I had updated AstroPhotography Tool and Cartes du Ciel. I have also included some catalogues, Burnham Northern and a Deep Sky Object catalogue for CdC. In future, I will be able to find the Arp galaxies.
With galaxies in mind, I had a go at imaging a galaxy in Pegasus. I managed 3 x 60 s at ISO 12800 (!) and 2 x 120 s at ISO 1600, so a LOT of noise. Somewhat to my surprise, DeepSky Stacker decided it could process this disparate data:
Wikipedia: NGC 7741 is a barred spiral galaxy located in the constellation Pegasus. It is located at a distance of circa 40 million light years from Earth, which, given its apparent dimensions, means that NGC 7741 is about 50,000 light years across. It was discovered by William Herschel on September 10, 1784.
Hopefully I will be able to get some better data when the weather allows.
