Edit: This is now 11.3hrs total integration time, my longest yet. Larger version available on
Astrobin.

This is 30x480s subs. I was hoping to get another hour or two last night, but the clouds came in early. Can't complain too much though, we've had a good run up here over the last week.
Anyway, I found something interesting doing this one. My dodgy pier doesn't hold alignment very well, and all of last nights (10 used here) subs I thought were throw-aways due to field rotation. I should have checked my alignment, but I didn't.
After stacking these less than great subs with the other 20 from the previous night, the eccentricity was still only 0.44 (as opposed to mid 0.5s to high 0.6s). I just integrated them to see what would happen, but I think in future I'll be using more of my "bad" subs. Honestly I wouldn't even know if I didn't know ;-)
This is a pretty dodgy processing job (I even used USM instead of decon), I'll do a better job when I get more data. Pretty happy with it so far considering there's only 4hrs of data here.
