Copeland's Septet Now with RGB

[DaveS]

Work very much in progress.

This is just 4 hours 40 mins (28 x 10 min subs) with the ODK 12 and ASI 533MM. I'm posting because I don't know when I will get the chance of collecting any RGB data, it may be next year now.

Initial Sigma Stacking and Gradient Reduction in AstroArt 8, then BlurX, NoiseX and GHS in PixInsight. I didn't like the huge gradient from the bright star bottom left so threw it into Graxpert which got rid of the gradient, but may have left a hole around that star, not sure. A final Histogram Stretch on AA8 to bring the range down before saving as a PNG.

I need a shed load more data, but when I'll get it is anybody's guess.

Last night (16/4/24) I managed to collect 4 hours of RGB in Bin 2 despite the very bright moon. Initial stacking and Gradient Reduction in AstroArt 8. One of the Blue subs didn't make it into the stack, but the rest were combined and sent to PixInsight for SPCC, BlurX, NoiseX and GHS (Which I'm still getting to grips with). Graxpert was used on the resultant RGB to knock down the very bright halo around the star at bottom left. Brought back into AA8 for LRGB synthesis, and slight Saturation Boost. Saved as PNG and JPEG. JPEG posted here as the PNG is a bit big.
