I'm using the ASIAir Pro with AZEQ6-GT. The above image was 14 x 30 sec exposures. I'm not sure how much it moves over ~10 minutes.
BTW, no dark or bias frames were used.
Thanks Dave. That was the last of three 18 × 30 sec exposures I took - with the darkest sky. BTW, all these were taken through an Optolong L-Pro filter. It's proving to be money well spent!
The width of the image is approximately 2.2 degrees.
Cloud cover prevented any views of the comet last night. It was also incredibly warm - about 34C at 9pm !
