I took this shot from my backyard about 3 weeks ago during an all-nighter (the 3rd of 3 in a row - yawn!).
RCOS 12.5 inch, Tak NJP mount, modded Nikon D70, 3 minute unguided shots after spending some time drift aligning (45 minutes or so).
I kind of cheated on the drift alignment in that I went only to one star - Canopus, very high in the sky and used it for both alignments.
The RCOS is a sweet scope and gives great visual images that are not far from refractor sharpness. Its a bit of a beast to set up and break down each night though so it needs to be more permanently mounted.
