Sometime last year after completing a long session on the Crab Nebula, I turned my C9.25 to it and took a 20 minute Ha exposure at F10. The little bit of detail that came through made a big impression on me, and so I planned a kit upgrade to get a proper image done at that scale. One C11 EdgeHD and Atik428ex later, here's the result. My EQ6 is working at its limit, but performing admirably under the pressure of providing a stable platform for a rig running at 2800mm focal length. The resolution is really pushing it too, 0.67 arcsec/pixel, but I wanted to see what the scope could do, so any time there was a clear hour or two, another few subs were added to the total mix. I've really enjoyed this one, it has kind of made up for a dreadful year of weather and cloudy skies. I have a new reducer on the way for the scope, and possibly a new camera too, so will be looking for some new challenges in 2013. Full details below, thanks for looking.
