Reflection Nebula NGC5367
25-Apr-2018
NGC5367 is a reflection nebula 2000 light years in the Centaurus constellation. The bright blue stars illuminate the otherwise dark molecular cloud complex.
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.
