Description

1st image from the revamped 200PDS and ASI1600MM Pro. Many projects half done, others ground to a halt with issues so wanted something quick and easy data in a night. So wrong image scale, stars blown out with subs too long, and not centered properly but lots of learning with processing mono data and solving a new set of problems.
