It looks like the HST has discovered two new possible satellites around Pluto, bringing its total to three. Here is a link to the article with an image:

I guess I won't be seeing those from my backyard observatory. Ha!I still have to try imaging Pluto itself sometime. Tom

Right Tom ... Even Uranus & Neptune are difficult to spot with a good Backyard Telescope ;-)
Good Hubble images though, wonder why they never got these before ?
After 16 years, HST keeps giving us great images! |

I've seen Neptune's moon Triton using telescopes with apertures as small as 11". This past Summer I managed to veiw three of Uranus' brighter moons from the back yard through an equatorially mounted 12.5" Newtonian reflector using a StellaCam EX astronomical video camera. The trouble was that the disc of Uranus in the integrated video image was overexposed causing its image to swell out engulfing the two bright moons that happened to be nearest the planet at the time. Turning the integration rate down caused the satellites to dim out of view. Careful planning will be needed to catch those two when their angular distance is farthest from the planet. I just haven't got around to determining when the optimum times occur.

I have seen both of those in my scope, but I stil have to try a good image of them. They don't look like much other than a small green/blue disk though.
Did you guys see the new Mars shots from Hubble that were just released?

Uranus can actually be seen with the naked eye in extremely dark skies. I have managed to snap a photo of the disk...just barely resolved, on 1600 ASA:
