It's a bit of a 'test image, but it's turned out fairly pleasing if I crop all the bad bits out :D.
I'm spending most of my time testing the workings of the belt mod to my HEQ5 Pro and also testing why I get significant image drift over a sequence of guided exposures (a separate, pre-existing issue), which may be tube flex or some other issue, especially when imaging in the eastern part of the sky. That issue is limiting my exposure times, and so this is 12 x 3 minutes stacked with an earlier 4 x 5 minutes with the camera in a different orientation, so there are some extra visible diffraction spikes. All ISO800, EOS 60D, 150mm f/5 Newt.
