HCG 10 Finished (For now)

[DaveS]

I've had to call a halt to this as by the time I can collect more data it will be getting too far west, so...

3 hours Luminance (Bin 1) and 1 hour each RGB (Bin 2) through Baader Bessel filters with a new ASI 533 on the ODK 12 as an experiment.  A bit of a disaster as they have huge halos. Nothing like enough data and it shows. Stacking, Gradient Reduction and basic RGB combination in AstroArt 8. Darks, Flats and Flat Darks but no Bias as it stuffed up the calibration.

Then SPCC (On the RGB), Blur Xterminator, Masked Stretch and Noise Xterminator in PI, then back to AA8 for a gentle Histogram Stretch and LRGB combination. A bit of selective Magenta reduction to tame the halos a bit. Saved as a PNG.

For reference, that blazing searchlight bottom centre is mag 6.3 reduced to 6.58 by air mass according to Stellarium. North is up.
