Howdy all;
I had a night of pretty fair seeing on Saturn, I rated it 6 out of 10 on =
the
Pickering scale. This was in my backyard roll off roof observatory with =
a
Nexstar 11. I went up to a 10mm LV eyepiece to get to 280X. Cassini's
division was easy, the crepe ring was seen in the best moments and there =
was
a good view of the equatorial band on the ball of Saturn itself. =20
But the really fascinating display was the fact that there were several
satellites of Saturn close in to the planet. Three of them, Tethys, =
Dione
and Mimas formed a triangle near the rings. Tethys and Dione were seen
constantly with direct vision and Mimas was seen about 30% of the time =
and
popped in and out with averted vision. The two brighter satellites are
about 10th magnitude and Mimas is 12.7, a somewhat difficult object in =
close
to Saturn. Enceladus was held steady on the other side of Saturn and =
Rhea
was pretty easy further out from the planet.
After a chance to get a good look and take some notes, a wind storm =
started
blowing at about 25 miles per hour and it was time to button up the
observatory and write up what I had seen. I hope others had a chance to =
see
this interesting alignment of the bright satellites of Saturn.
Clear skies;
Steve Coe
