A repro of my data from early September, using some additional Ha data, new processing techniques and slightly improved aesthetic taste?
LRGB data captured over two nights in early September at the AAQ Dark Sky Observing weekend at Glen Aplin. Ha is from (light polluted) home.
Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon E series Gen 2 LRGB, Astrodon 3nm Ha
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Exposures: 7x900s R, 7x900s G, 7x900s B, 30x600s Lum, 31x900s Ha (10.5 hours LRGB, 7.75 hours Ha)
I think this is a significant improvement over my previous attempt although the halo isn't as pronounced. Still not 100% happy, of course

Constructive criticism is appreciated...
Cheers,
