'Helix' Nebula, NGC 7293 in Aquarius

I've re-stacked a set of previous exposures from 2014 with some recent frames to further reduce noise.
24 x 1-minute unguided exposures at ISO 3200 (taken 8 September 2019); 11 x 3-minute manually, off-axis guided exposures at ISO 1600 (taken September 2014).
Modified EOS 600D & Revelation 12" Newtonian reflector telescope.
Registered and stacked using DeepSkyStacker; curves adjusted in Canon Photo Professional; noise reduction via CyberLink PhotoDirector.
