Description

This is my first light with the Esprit 150. Data acquired with the ZWO ASI071 OSC. I started to collect light frames to check the field flatness, OAG performance etc, but the seeing conditions were very good so I ended collecting more than 6 hours in two nights! Processed in Pixinsight, I need to get rid of some purple and green casts due to Light Pollution. I think I am happy with the field flatness and the resolution/sampling (the image was re-sampled at 50% to reduce the file size).
