Thanks guys. Yes there are definitely limitations to the OSC but its nice to stretch equipment and see what it can do. I think at least another 4 hours could be in order ... and some shorter subs...and a few nights when the seeing isn't jumping all over the place like a tennis ball. The good thing about 6744 is its only going to get higher and better over the next 6 months
If I could get the diffraction spikes aligned and the image scale sorted out I'd take some Lums with my H9 to add to the galaxy.
