BEHIND THE IMAGE
Notes from the session
On a personal note, I am finally happy to get some fantastic natural star colours. I believe this is due to replacing my Astronomik Deep Sky Red filter with the older Typ2 Red, giving a slight overlap between red and green, which allows richer orange and browns.
