This is the first light for the new ROR and hopefully my return to frequent imaging. This is only the third image I've done in almost a year, with the other two being quite short integrations.
I may yet add more data to this, but I have to confess to losing motivation quickly once I get around the 10hr mark due to the diminishing returns in terms of SNR.
I did no flats for this, but instead did a synthetic flat using a novel (as far as I know) technique which I'll detail elsewhere. Won't work for every image but I cleaned up all the dust donuts and vignetting very easily without negatively impacting the SNR of the image.
Integration details:
L: 196x240" -15C bin 1x1
R: 12x240" -15C bin 1x1
G: 12x240" -15C bin 1x1
B: 11x240" -15C bin 1x1
Integration: 15.4 hours
Equipment used was that in my signature.
"Seeing" was actually poor / average for my location, which may be due to the construction materials of the new observatory and now required cool-down time for the scope.

Edit: More data! Now 15.4hrs instead of 9.6hrs. Added new thumbnail. Same old link for full res.
