On 22 Oct I had a go at EEVA with the moons of Uranus, using my CPC800 and the ASI224MC (and flip mirror)
The image with about 5 sec exposure looked exciting, with several little dots in a line around Uranus's overexposed blob. But when I analysed it later I found that I had imaged several 13th mag. background stars, and noted Oberon as a definite ID and Ariel as possible. The seeing was bad.
The moons are clearly within the range of this setup, so I will try again sometime and see if I can secure a set of stackable images. The Sharpcap live stacking wouldn't work on this occasion.
I needed Calsky to identify and eliminate the background stars, but it unhelpfully notes the moons as 'beyond the range of amateur telescopes.' The Sky & Telescope tool identified the moons.

On 31 Aug I took some images of the Pluto region with 102mm achro f5 refractor, ASI224MC. With the SLT mount synced to Saturn, the mount placed Jupiter and several Messier objects well in the camera field of view, so I was confident it should be capturing the region of Pluto.
Next day I plate-solved one of the Pluto images successfully and identified the brightest star near the position. Pluto does not show up though - too faint. The 15 sec exposure shows the sky background.

Here are some EEVA-style images made with a 102mm f5 Startravel, SLT mount and ASI224MC planetary camera. I don't claim that they are very good, but would point to the modest equipment used (the camera cost more than the OTA did) and the fact that these are single exposures of about 5 seconds.
I have previously tried imaging globular clusters with a C8 but the results were dire.
One should also compare them with the eyeball view through a telescope of twice the size.
I also tried imaging the region of Pluto, but on interpreting the result it appears that I missed the planet's position and also was not giving enough exposure to pick out objects that faint.

Here is a EEVA-style image of Neptune and apparently its largest moon, Triton. I had been trying to image planetary nebulae before aiming the gear at Neptune, and noticed a faint smudge below the severely over-exposed planet. It was possibly easier to see at the time than on the processed image attached (between planet and arrow). It seems to match the position given by Sky & telescope's Triton Tracker.
At around mag 13.5, Triton would normally be beyond the reach of a C8 used visually even in ideal conditions.
Image is inverted, taken 12Aug at 22.40 UT. CPC800,ASI224MC, flip mirror. Gibbous moon.
