I doubled down on my derotations tonight. Here's a set of five 400-frame stacks:

Very polished looking and tones as always look masterful.  With all those de-rotations 'Turn back time' might be your theme song!

Fascinating what time of day does to perception. At 2 am, the image above looked bright and colorful on both my laptop and my phone screens in the dark. Now at 2 pm, it looks dark and mysterious on both screens—not my intention at all! So here's a stab at a brighter variant:

+1 for the second.

First image looks like there was too much gamma correction used.

Some more tweaks…Astronomy Tools "Local Contrast Enhancement" action as a darken layer followed by CS5's noise removal with detail sharpen. And an inclusion of the color profile in the JPEG as a cross-screen experiment:
