Another M8

[LKD (Luke)]

Discovered a few things with this image, found a way to critically focus manually with only a coarse focus knob on my AP Star12ED, discovered multistar guiding in PHD2 and also unsharp masking. 15 x 300s subs in Ha and OIII, 30 x 300s subs in SII, QHY294, AP1200 mount.

Looks excellent. Got a high-res somewhere?

A great result Luke. Noise in the full res image is very apparent and needs taming.

Flats/Darks all need to be taken at the same mode, gain and offset
to calibrate well.

Tack sharp across the frame...very nice indeed.

Hi Peter, Thanks for the comments and guidance, no flats used at all, and need to improve my darks. So will start to incorporate this.
