Here's last night's efforts. It seems I've finally resolved the guiding issues that have plagued me for a year by switching to a lodestar. I think the DMK41 was just pushing too much data through the USB hub.
Anyway - also a first experiment with 2x2 binning the RGBs, and using 2 hours of 30 minute H-alpha subs for the L channel binned at 1x1.
Scope was the FSQ106, mount a G11, and camera the QSI683.
Comments and advice welcomed!
cheers,
Andrew.
