I've been playing around with my last M27 tonight. This is a crop. For a bit of fun I added some diffraction spikes. (I miss my newt)
1 hr 55min @ ISO800
Canon 20d
ED 80
Great details in the neb but the spikes are a bit overwhelming IMO. That reminds me of a shot I did of the pleiades on a newt. I used 10min subs to try to get as much neb as I could and not have to shoot many of them. It backfired on me. The shot looked like a Xmas tree.
