yep... and at that point you're just trying to compete with Hubble and JWST.
I'd say it's cool to try and take nice pictures of the Moon or the Milky Way, but anything beyond that is better left to NASA!
I am an astro photography kind of beginner but have had some success with the basic deep sky nebula, galaxies and nebula with my camera on a tracker.
So I tried this technique as I had read that the video on the R7 is good for this. SO, my R7 with 600mm RF, F11 +1.4x TC. (F16 not a problem as Jupiter so bright at the moment). R7 1/50th sec cropped 4k video mode, giving a further increase in magnification and also this mode isn't compressed I believe. So after focusing (tricky) I took about a minutes worth of video across the frame and stacked and processed the result using various free software designed for this purpose. Easy to just Google that bit. I was quite pleased as you can make out the moons Europa above, Gannymede below and Io is just a dot touching the edge of the planet in the bottom left hand corner. Callisto is cropped out of the frame.
