Deep Lagoon, Triffid in HA

Hi
I used the 300mm lens from Bert, and the Baader 7 Nm HA filter to image this area under a fairly dark sky (for Newcastle)
7x 10 mins ISO 800, 300mm f2.8 flourite lens

Full size version here

Using just the red channel gave an image with saturated inner areas of the nebulas, so I used the green channel as an unsharp mask, preserving inner detail and keeping the faint extended stuff
