Hi all,
Here's an image I did a few weeks ago. It's IC4628 and accompanying nebulae in Scorpius. It's a 60-minute exposure (20 x 3-min sub frames) at ISO400 with my modded Canon 300D on my observatory mounted GSO 12" telescope.
Notice the small nebulae bluish nebula surrounding the bright star (lower left of centre image) and the fainter nebula just to the right of that.
