two out of three aint bad!

I had to give up on my attempt to fit all three of the leo trio into a 2 frame mosaic as the light-pollution gradients just killed it. However, each of the two frames wasn't so bad with a bit of cropping, so here's M65 and M66. It's certainly possible to see the bar in M65, and the internal structure of M66 shows that these guys have had a pretty hard time in the last 800 million years.

Scope was a 16"f3.6 with Wynne corrector, camera is a QSI683wsg with astrodon filters. This about 3 hours of L in 5 minute subs, with 1.5 each of R,G and B.
Constructive criticisim welcome, as is speculation on whether or not I ran decon on the luminance channel.
cheers,
Andrew.
