Description

Rho Ophiuchi Cloud Complex and IC4592 The Blue Horsehead Nebula

Conditions were not the best. This was shot at 85mm. It remains one of my favourite night sky subjects.

I had an issue with framing due to some physical constraints in my equipment; hence the somewhat unorthodox juxtaposition of the various astronomical elements!
