Matt, Doug & Les...Glad you like em guys, still pretty new to this so learning new stuff all the time, I can see why people get hooked on this hobby.

Struggled with the colour on M31, had a persistant green tinge, correcting in shadow/highlights colour helped but getting bluer arms gave a nasty pink core to the galaxy.

Planetary nebula have such beautiful colours, would love to get a nice collection of them.
