I decided to shoot with my big scope (Celestron 9.25 on my Losmandy G-11) and Pentax K-1 last night. My first time imaging this in 3 years.

 

40x300s

ISO 800

Guided by the Lacerta MGEN 3 connected to the Celestron finder scope as a guide scope (I had to remove the eyepeice section and hook the camera into the diagonal and thus focus was hard to achive for the guider)

It was pretty windy in the early part of the night and I had to toss about 10 of my original frames.
