I finally got around to processing some non-asteroid data (the weather has not cooperated for several days). I took this image on the evening of the 29th of July.

Even at roughly 3 billion miles Neptune is bright enough that I had to take a short image (5 sec) to prevent over exposure. As indicated, one of the bright objects immediately to the right of the planet is Neptune’s largest moon Triton.

Star-like Neptune with two small objects adjacent to the planet. The top one is the moon Triton; the bottom one is a background star.

Neptune & Triton [CV:1x5s]

Triton is the 7th largest moon in the solar system (our moon is fifth on the list). Triton is somewhat unique in that it is in a retrograde orbit which supports the current theory that it is likely a captured Kuiper belt object. Imagery taken during Voyager 2’s flyby in 1989 shows a very thin atmosphere and active cryovolcanism in the form of nitrogen geysers.

After getting some imagery of Mars and Neptune, I stayed up long enough to get some of Uranus. Neptune is right at the limit of my planetary equipment.

Neptune

These planets are so far away (2 and 3 billion miles) and thus so dim that I could only get useful images at 4 frames per second. The atmosphere moves a lot in a quarter of a second, so I ended up throwing away quite a few blurred exposures. I was pleasantly surprised with the amount of color evident in each final image.

These copies are zoomed by 4 times to show the color barely detectable in the original images.
