I did collect LRGB data on Sat night, and I've combined this with additional data taken at Leyburn some time ago. All up, details are:
LRGB 25:15:15:15 mins
Lum 2x10mins (unbinned) and 3x5mins (binnedx2)
RGB 3x5mins (binnedx2)
Other info:
Elevation: approx 15 degrees
Seeing: very good (for 15 degrees!)
Tracking: average
These low down to the horizon images are always tricky to process and colour balance and the supernova image and colour is affected by combining images before and after the event. The stars could do with a far gentler treatment.
I'll have another go at a later date, but suspect it will be lots more work for relatively little improvement. I'm very happy with this compared to my previous M51 efforts all things considered.
