imaged the Helix again (Halifax)

Wanted to have another go at the Helix Nebula aka NGC 7293.

Avoiding the Moon... (with a 5% maximum filter).

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

Helix planetary in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots.

Helix planetary in hydrogen

H-alpha only, 60 seconds subexposures, 10 stacked shots.

In a separate imaging job, I've requested the RGB data for this Finest NGC object...

Much better results from before, from 1 Aug '18, thanks in part to longer exposures.
