- The skies finally cleared in Maryland Sunday night. As mentioned,
- I picked up Comet Swift-Tuttle in 7X35 binocs as soon as it got dark
- (~5:44 pm) and soon thereafter star-hopped to it in a 12.5" f/8
- Newtonian. Used a 55mm, 32mm, and 16mm eyepieces. I recommend
- that anyone who can get to a 'scope take advantage of this (brief?)
- clear spell to put some aperture and power onto it. It had a lot
- of coma with many faint variations in the fuzziness. I thought I
- glimpsed (averted vision and shaking the scope) a big curve like a
- bow-wave curling around and away from it. It looked like some of
- the drawings I've seen of classic comets. Confirmation (or NOT)
- would be welcome.
-
- BTW, I saw Comet Halley in this same scope about fifty times and even
- with the by-now-rather-thinner mirror coating, this comet compared
- favorably with those sights.
-
- So get out there with some big guns and don't be afraid to crank up
- the magnification. Photos won't do it justice, as your eyes can
- pick up more range of brightness (and faintness) than paper can hope to do.

- (P.S. - a fresh posting quoted a discounting of the collision threat
- next time around - but how about an older post that said that
- _eventually_ the comet, or what's left of it _must_ be swept up
- by the earth? Until it finally dissipates, there is nothing else
- to stop it until it happens to find terra. Maybe not on the next
- pass, but the 50th?, the 1000th????)
