Description

This is a two panel mosaic of the area around the Crescent Nebula in Cygnus. I wanted to capture the wavy ring of Ha nebulosity surrounding the nebula and needed a second panel to do this. The Crescent Nebula is created by the Wolf Rayet star WR 136, and I've also managed to include the nebula associated with WR 134 towards the bottom of the frame. As well as being labelled NGC 6888, the Crescent is also known as Sharpless 2-105. Sharpless 2-104 is the bright nebula to the lower left.

Taken with an OSC camera with dual narrowband filter, I separated the colours and processed as HOO, trying to bring out the blues a bit more. Can't really compete with mono and very narrow filters this way, but it's worth a try, particularly at this time of year! Didn't really help with the soap bubble much though!

Anyway, as this was taken over three nights encompassing the summer solstice at 51 degrees N, I'm quite pleased to get anything presentable!
