returned to the Saturn Nebula (Halifax)

The Burke-Gaffney Observatory imaged a couple of targets for me this evening including NGC 7009. Two years ago I imaged the Saturn Nebula. Exposed the luminance then for 15 seconds. This time I shot faster.

All images: FITS Liberator, GIMP. North is up; east is left.

Luminance only, 10 seconds subexposures, 15 stacked shots.

Hydrogen alpha, 30 seconds subexposures, 15 stacked shots.

Ionised oxygen, 30 seconds subexposures, 15 stacked shots.

Arguably, they are still blown out, it is such a bright object.
