Description

This is a very weak and rather challenging Ha object in Cygnus. Last night I collected 25 x15 min of Ha to add to RGB data from a year ago (posted previously). It helped to bring out the dragon as well as surrounding nebulosity. I used the Esprit 150 with TS 3" 0.79x reducer and ASI1600MMpro. The moon was up but I think the 3.5 nm Ha filter did a good job at blocking out the moonlight.
