Managed to get the left frame of the Sagitta mosaic last night with anothe 5-hours of 10-minute subs using the 200mm lenses and the 2600MC Pro OSC CMOS cameras. So that is the whole of Sagitta covered.
Apart from the nice Milky Way background, this is a stunningly unimpressive constellation and this image can only be saved as a “pretty picture” by getting the 3rd frame on the right containing the Coathanger cluster. If I get the weather in time, that will be my next target.
