Description

Trying (and mostly failing) to use CometAlignment in PI to get a stars-only/comet-only image. Better than having a trailed comet head, but still a long way to go on this learning curve--any advice gratefully accepted!

As an aside, pretty neat that there are two barred spirals in the same field. I think I will come back here another time--nice field to shoot.
