Melotte 15


Recommended Posts

OK, let's see how this goes.

Melotte15 in SHO, 9 hours [sII], 4 hours H-alpha, 12 hours [OIII]. TS Photoline 130mm f/7 apo, 3nm Astrodon filters, ASI1600MMC Encoder guided on ASA DDM60


 Stacking in AstroArt 7, initial stretching of individual stacks in GIMP, back to AA7 for RGB synthesis and ratio, into Affinity Photo for channel mixer, curves, selective colour, denoise and clarity., with final scaling for export.

Need more [sII], and possibly H-alpha.

Thanks John and Mark

I'd had a go at this last year with the Trius 694 on the 130 apo, but had run into stupid problems with of-orthogonal orientation resulting in badly skewed alignment edges leading to big cropping. I also managed to get a lot more data this time leading to a cleaner image.
