Thanks for the encouragement. I'm using an unmodified Canon EOS100D attached to a Skywatcher Esprit 100ED. This was 26x 60 second subs at 800 ISO with about 15 darks together with bias and flats. The camera works well on bright targets but not so well on dimmer targets. I've been trying to get the Horsehead nebula before it disappears over the horizon using 180s subs but have been slowed down by clouds, moon and even neighbourhood blackouts. I've accumulated about 40 subs but the images are still really noisy and I may not finish it until Orion comes back up in the east!
