Thanks Ross! Yeah, got a few miles under the belt now. My secondary housing came loose a couple of weeks ago so I had re align and tighten that up then re collimate the hyperstar lens. I think I've got it back to where it was.

Cheers Ian!
Backyard EOS was reporting sensor temps of 27 c to 29 c during this run. So yeah, pretty hot. I think I'll be going mono CCD in the future, until then its lots of lights and lots of darks.
