28740Deimos in the 175/8
- Nov 1, 2005I've been watching Mars.. again.. At 396x in a pair of 6mm monocentric
eyepieces, I can easily lock on to Deimos and hold it in averted vision,
with Mars sitting there lighting up the eyepiece a good bit. If I shift
Mars just out of the eyepiece, Deimos becomes dead obvious. I can almost
grab it with direct vision then, but not quite.
The show changes fast !
While watching Sinus Sabaeus crawl across Mars, I just knew it had to be a
martian moon that kept popping in and out of sight off the port bow. In
order to determine what it was, I noted it's distance from Mars in
Mars-widths, and what angle it was at relative to Syrtis Major and Sinus
Sabaeus. Came inside, ID'd it as Deimos using Skytools-2, and then warmed up
for half an hour. Deimos has obviously moved a bit on return.
You can see it's pretty well off of Mars as I've seen it tonight (white dot
to the right:)
Phobos really burns up the tires. Its crossing Mars right now, which I think
takes a bit under an hour. I'm planning on defeating it as well tonight,
about 120 minutes from now. Unless it's in the birch trees.
