Nicely done Mike!
A photogenic albeit small spiral. Love the background galaxies visible through the arms.
I'd probably add a bit more colour data though - to minimise colour noise.
I envy you being able to capture an image in one night. I managed to get 6 hours of Luminance on Monday. A couple of brain fart issues wasted some time.
And I still need more Lum before I do RGB. I probably need another 2 nights at least! And the weather reports don't look good for the next week.
