    Here's a sort of uber-imaging setup with a 9.25" aperture/2350mm f/10 Schmidt-Cassegraine compound scope with an afocal imaging setup about 15 years ago: Sony TRV-900 3-CCD VHF camcorder with full man. controls, SS down to 1/2 sec connected to a telescope eyepiece (this is the "afocal" setup) which is connected to a 3X TC (Barlow lens in astro lingo). The Jupiter images filled about 2/3 frame height with the Sony at about 10X zoom. This method makes finding the object pretty easy zoomed out, works well in spite of the huge # of optical elements involved, and zoomed-in gives enormous mag. - maybe ~ 20-25 meters EFL @ f/100?
    The film clips were processed in Registax, which selected the sharpest (due to brief reductions in atmospheric turbulence), stacked 400-600, which accentuated common detail features, than a complex multistage "wavelet" sharpening routine. The first Jupiter image was from the steadiest "seeing" conditions I've ever had - in the Florida Panhandle. The Mars image at it's historic closest approach in 9/3/03, from southern Mexico.

    Another attempt with the GH3 and the 1.000mm catadripotic tele. Jupiter and four moons, Europa, Io, Ganimede and Callisto.

    5 years ago i made a photo of the ISS with my GH3. I made it in photo mode with a old russian 1.000mm catadioptric lens. It was incredibly difficult to find the tiny point in the viewfinder and mantain the hight speed across the sky. I made a few dozens shots and one was sharp. It was pure luck at 1/125s. This is a 100% pixels crop.

    It is easy to attach m4/3 camera to telecsope like in this video:

    This video of the international space station passing the moon has become quite famous on the internet, demonstrating as it does the unusual abilities of the Nikon P900, a super-zoom consumer camera which costs around $700.
    Can we do better with a 'proper' camera?

    Andrew, the problem with a much larger sensor than the tiny video chips of yore is that you have to use a significant zoom lens on the camera (or a long FL prime) to couple to the scope eyepiece/TC train. I've tried my GH4 w/ the compact Panny 14-140, but just too bulky, with a relatively small circular image shown, or no focus-able image all. My next iteration was the Sony HC1 FHD camcorder, but never found suitable astronomic "seeing" to warrant the time and effort of setup with the 9.25" f/10 scope.
    What I have done with it is total solar eclipse recording of solar flares and detached prominences, but with a very compact and excellent 4" 1000mm f/10 reflex scope w/ tube length only 8" using an eyepiece coupled to the Sony lens, but no TC. First pic below with the VGA res. TRV-900 of the striking detached prominence - Africa '01; the second with the FHD Sony of the "hedgerow prominences" I've not seen imaged in this detail - Turkey '06. For the recent eclipse I viewed and imaged from Madras, Oregon, I used my GH5, Canon 100-400-II w/ 2X TC shooting 4K in ETC crop mode (2.7X crop factor), plus 2X dig zoom or this to 1080p res and 5.4X factor = 4320mm EFL. Tech. screwups on my part nixed any views of the pretty unimpressive flares at this mag.
