Not ideal sky conditions at the local farm stay last Friday (stars twinkling madly and the moon) but a clear sky none-the-less. Was keen to have a crack at SL 17 (the “Dark Wolf’ near the Scorpion’s tail). Processed it first without Luminance filter data, using the Ha as luminance, which made ‘the head’ quite wispy and light, and then processed it with the Luminance filter data, which really made the whole area much more opaque. Then....
....did it all again and got a much more natural look. Lum and Ha combined for Luminance and Ha as the Red channel with various adjustments to reflect the RGB colour when combining it all. I think a much better result. Astrobin:
