More deep HA images with Bert's 300mm lens
Howdy
Took advantage of the warm and very dry conditions last night to shoot the following
IC 4628 4x5 mins iso1600
M42, 7x5 mins is01600 masked with a 5x2 min iso200 image
SMC, 3x5 mins iso1600
Horsehead Nebula 4x5 mins iso1600, cropped as house was in edge of frame.
All taken through Bert's 300mm f2.8 flourite Canon lens, with Idas uv/ir and Baader 7Nm Ha filters, with modded 350D camera. 6 darks for the ISO 1600, 1 for the ISO 200 images, a flat and an offset, processed in Iris then Photoshop and Noiseware.
