Up close and personal with the Southern Ring (NGC 3132)

The Southern Ring Nebula (or Eight Burst Nebula) aka NGC 3132 - a tiny but very interesting planetary nebula in Vela.

I've had a few stabs at this one but this is the first time I've really poured some serious hours into it - 22hrs over 6 nights. I was fortunate enough to have some absolutely spectacular seeing conditions on 2 nights (the rest on the good side of average).

Approx 22hours using the L-Ultimate dual narrow-band filter in 120sec & 300sec subs + 45min RGB in 30sec subs for stars. Most was binned 2x2 but the nights of excellent seeing I left un-binned.

A very challenging target to reveal both the very faint outer shells along with the intricate detail nestled into its bright core - all the while trying to maintain natural looking colour and detail. GHS and range-masks helped greatly and I was pleased to reveal the faint outer-halos that I've seen on a couple of other images. Hopefully I didn't overdo it too much but interested to hear your thoughts too...

Stacking, channel extraction and LP removal in APP, processing in PI and final tweaks in LightRoom.
