How was the seeing last night?

- Last night I was doing volunteer "work" at Lick. Mars looked
quite good when it was relatively high in the sky but you could
still see the edges of the disk wiggle quite a bit. How was the
seeing at the other sites last night?

- Lake Sonoma - wobbly edges until well after 11 PM. Then, I don't know if
it was the elevation of the planet, improvement of seeing, or both, but
around 11:45 or so it started holding magnification quite well up to over
300x. After midnight it was solid more than 75 percent of the time.
I used a stacked 17% moon and 80A filter with a 7mm Nagler (290x) for
good, detailed views on the 18". Dang, that baby is bright!

- The La Honda Star Party was a success last night, thanks to friendly TACos
and PAStros who brought scopes to share with an avid crowd of locals and a few
Seeing was decent early on, dark enough to see dark lanes in the Milky Way;
some minor large-cell turbulence until about 11 O'clock when it got REALLY dark
and the atmosphere settled down. Views of Mars were quite good as it got
higher. At 2 AM much detail was visible in the surface markings, and it was still
Another Star Party is planned for September 20.

We had one of the best nights I've ever seen here at Plettstone last night.
I was getting mag 15 galaxies easily in the 15" F5 scope. M33 showed
structure like I have never seen before in its arms. The star clouds in the
galaxy had a three dimensional affect. All of the prominent hydrogen
regions were clearly visible. It wasn't long before most of us were
visiting as many Messiers as we could find. It was a treat to see such
detail in familiar objects. M74 showed clear spiral arms and dust lanes.
It's never appeared much more than a blob in any instrument I have looked
through. All of the globulars were resolvable right to the core. This was
true in all the big aperature scopes here. We even spent time looking a the
globs well south of Sagitarius and they were quite spectacular even being so
down in the muck.
I could go on and on, but I've got lots to do to get ready for OSP.
