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.

RASC Finest planetary nebula NGC 7009 in luminance

Luminance only, 10 seconds subexposures, 15 stacked shots.

Saturn Nebula NGC 7009 in hydrogen

Hydrogen alpha, 30 seconds subexposures, 15 stacked shots.

Saturn Nebula NGC 7009 in oxygen

Ionised oxygen, 30 seconds subexposures, 15 stacked shots.

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