Object name: ERIS
Eris is a dwarf planet that is almost as large as Pluto and much farther away. In fact, it is the most distant object known to be orbiting in our solar system. Space probes like Voyager 1 and 2 are even farther away but aren't orbiting. Sedna can get farther from the Sun than Eris but currently is closer. So Eris currently marks the most distant known object in our solar system, about 3 times the distance of Pluto right now. The image I ran was cropped from a much larger image. That turned out useful. On Jan 22 and 24 (all UTC) I reimaged Eris. When I compared the new images I realized I was seeing some of the same stars. In two months it had moved only a fraction of my field of view which is only about 34' wide. But I'd lost the original position just out of the frames on the left. Also since the temperature was 25C colder the image scale and distortions in the optics didn't match. RegiStar, however, was able to correct for all this as well as other problems and registered all three images nicely. I then combined these to make a three frame movie. I left the circle I'd drawn around Eris in the movie for all three frames. I should have circled the other two positions as well as it may be hard to find toward the upper right-hand corner (northwest corner). When I imaged Pluto several years ago it moved as far in two days as Xena - er Eris (I still prefer the rejected name) has in 2 months!
