I was taking photos of Andromeda and while camera was shooting I watched stars with my telescope. Star chart showed that Uranus and Neptune are south and to that direction I have a clear view. I had already photographed Uranus so I aimed for Neptune. I probably saw it on telescope but didn't recognize the star like object for a planet. With camera I had more luck. Neptune was in an easy place middle of stars visible on naked eye. I pointed my camera there and took couple of shots.
Afterwards came the more difficult task of comparing images to a star chart. KStars didn't show enough stars so I tried Stellarium which that too showed only stars up to magnitude of 10. That wasn't enough to recognize which spot is Neptune. I fought with it for a while by adjusting settings and downloading more star charts... Until I realized Stellarium has to bee restarted to make it use those new charts.
Here it is.
|Neptune. At least according to Stellarium star chart.|

And here's the original whole frame. Good luck finding Neptune there: http://www.flickr.com/photos/96700120@N06/9997488305/
I still need photo of Mercury. Otherwise I have (some kind) photos of every planet. I've seen Mercury on naked eye and on telescope but at that time I had no camera to attach to telescope. Also my photos of Venus, Mars and Saturn are from a time before I had a Barlow.
