IC4633 is a small, face-on spiral galaxy in Apus. By itself it isn't that exciting, but it is embedded in Mandel-Wilson 9, a large integrated flux nebula. Only a small part of MW9 is shown in this field.
Data captured at Astrofest this year over several nights. Maximum altitude was only a little over 30 degrees, so this was in the light-polluted Southern soup every night as well as close to the pole and challenging for guiding. Fairly happy with the result anyway...

Constructive criticism is always appreciated. I did push the colour pretty hard, as is my wont
Cheers,
