Helix with Bert's lens
Howdy
I turned Bert's 300mmF2.8 lens onto the Helix Nebula thismorning.
9 x 5 mins ISO 400, UHCS and UV/IR filters installed in back of the lens. Weather was rather horrible, with broken cloud, conditions not that dark, having to dodge cloud between exposures. Manually guided with a cheap catadioptric 3 inch "focal" brand scope that was an ex Halleys Comet special, attached to my mount alongside Bert's lens.
I used the masking technique to bring out the faint outer detail. I want to go deeper next time if I can.
