Seized the opportunity to go to Leyburn dark site on the weekend. Wanted to give the new Williams Optics Flattener IV a real workout on the ED80 doublet. I'm very happy with the results - I think the little ED80 knew what was coming if I couldn't get these flat fields sorted out so she really turned it on for me.
The second hour of data has all been corrupted, something was going on with the downloading of images from the camera to computer. By the time I sorted that out, it was late, M45 had flipped, and my battery was running low. I had planned to just image this most of the night, but equipment issues meant I only ended up with 9x4mins plus darks and flats. Still a bit of noise around, but did my best to tease it out. Still learning little PP tricks.
First time I'd used flats too. Very happy with the results of that too.
All in all I'm pleased with the result now and look forward to collecting more data to enhance this beautiful and serene cluster.
