Constellation of cygnus starting to get well placed for imaging this month.

Cygnus is chock full of interesting bright nebula suitable for narrowband imaging.

One of my favourites the cresent nebula. Trying to capture more of the faint oxygen shell this time.

Increased oxygen exposure to 30 minutes. My mount had my problems coping with this.

Data collected on two nights. 26th, 27th May 2017.
