Last night Mackay finally got cold. And man was it cold! 5C out with the scope. So here is my M20 with the 10 inch F4. It's a bit soft as seeing was crud and focus was hard to stabilise. But it's better than a slap in the face with a wet fish, I think. I wanted to get as much outer blue reflection nebula as possible. I think I got a reasonable amount.
GSO 10 inch F4 Newtonian, 584 x 30 seconds unguided on an HEQ5 Pro, Baader Semi-Apo and Astronomik CLS filters (separately not stacked), Baader MPCC MKIII and standard Pentax K-5.
