Greg's image of the Lagoon caught my interest as I imaged it a few weeks ago with the same sensor, though a much smaller scope.
I didn't have the time for a marathon effort.... just 20 minutes infact.
What surprised me was the S/N is still pretty good, despite way less photons coming down the pipe.
I've posted the image in HD res, so yo'all can have a good look
