Description

I shot a handful of test subs on this one over a few nights in early April, while I was waiting for the Antennae Galaxies to clear the trees. It certainly fills the frame and looks pretty fierce at this scale!

This one is about 1/3 of the time I typically devote to luminance. We'll see if I have time this year to add to it.

Pardon my dust.

Rev A - Initial Luminance process of 30 frames

Rev B - Slight reprocess

Rev C - 30 more Luminance frames added along with RGB data. Due to some rotational alignment problems the crop is a bit tighter. I toned back some of the stretching which was initially pushed a bit far.

Rev D - A touch of star reduction to dial back the bright ones.
