This time I setup to try my hand at a webcam photo things turned out
much better. It helps that Mars was not jumping about the frame like a
blob of jello. The first time I setup last week the equipment was
running great as I figured out how to use the software, but I didn't
even think about processing what little material I did save to disk. I
did store a few sequences of Mars and the Moon, as a great example of
bad seeing! The scintillation of Vega also makes great video.
Has anyone considered analysing the optics of the telescope by using a
webcam at high power and stacking a stellar image to view the airy disk
and diffraction rings?
Last night the seeing was OK, but not great, maybe a 6 with a bit of 7.
So I shot sequences of 600 frames at 1/1000 of a second hoping to freeze
what movement there was. The resulting image is 500 frames stacked. I
don't think it is too bad for my first real attempt at this sort of
imaging. I still need a couple things, a barlow, and maybe an IR filter,
but even without it did work...

I can't wait for Jupiter and Saturn!
