Looks pretty good to me Steve!
After 3 mornings of rain and clouds
I had another session this morning and finished up with 8000 frames. Everything look pretty well focused and exposed, a 300 frame stack shows already the crater ray system.
My computer is chewing on the data for the rest of the day, probably tonight I'll have the complete unsorted 8000 stack ready and can chuck everything on CD so I can empty the harddisk for the next session...
Which makes me wonder, I noticed that the unsorted stacks give results as sharp as frame selected stacks, only the unsorted one needs a bit more sharpening. I tried this a few times with Jupiter, and if I compare two separate images shot a few minutes apart the unsorted stacks show not only the same amount of detail as the sorted ones, but their detail is also more consistent.
With al these unsorted stacks of Mercury I start to notice the same thing, if I stack 60 very crappy frames together, Mercury's disk still shows up with a sharp edge, as long as the telescope is exactly focused.
Cheers,
