Hi All
I finally managed to get my William Optics ZenithStar 66 SD Doublet Apo to focus with my SBIG ST2000XCM last night and madly rushed around the sky checking the field of view while there was no wind ... it had been virtually gale force easterlies the previous night. Anyway this is a single 10 minute exposure @ -5 degrees ( hot night ). It's quite soft as I didn't have my UV/IR filter attached because of the imaging train configuration ... I will have to take a look at adding it in for the next time
