CSC predicted that seeing in Toronto in the predawn would be good so I woke up at 3:30 and found a spot beneath my huge silver maple that gave a clear SE view. I wasn't able to wait for Jupiter to reach apogee so captured it as the sky was starting to lighten just before 5 AM. Seeing was quite stable. Captured with my C8 @ f20 and PGR Flea mono camera, stacked about 350/1200 per RGB channel.

That will be way better than anything I get this year, as Jupiter will at peak altitude only be 26° above the horizon up here.
My summer astro project is to retrofit some mirrors into a 16" truss dob that I acquired and build a Poncet platform to allow planetary imaging. Stay tuned!
Very cool. I searched for "Poncet Mount" via Google and came up with several example and plans. Are you going for a single or dual motor version?
At least with a 16 mirror, you be gathering so much light that you can run at much lower gains and higher frame rates and maybe freeze the seeing between frames.
