M27

For my second attempt on M27, I used my new Esprit 150/10micron GM1000HPS combination (the result of the first attempt is in my Deep Sky album). This image represents about 10 hours integration. 

From a processing perspective, I decided to blend the Ha into both the Lum and Red channels using an Adam Block technique that I learnt through his "cosmic canvas" tutorial videos.  Since the Ha is very strong and would obliterate the RGB information I decided to only blend a small amount into the red channel. Since I was interested capturing the faint outer halo, I decided to raise the level in this particular region. 

I was reasonably happy with the result - you can just about make out the outer halo, star colours are reasonable and you can see some inner structure to the nebula.
