Observing Reports / Re: Dinosaur Point rides again
« on: October 16, 2017, 05:33:13 AM »
Nice to read your report, with rain forecast for Thursday I am wondering if it's somehow possible Lake Sonoma might be ok by Saturday, but if not Dinosaur Point is definitely on my list. Thanks for your help.

What do people do when finished observing, given there is no overnight camping, just pack up and leave? Are there any good places to stay overnight not too far? It would be about a 3 hour drive home for me if I come. Thanks.

Any idea how Dinosaur Point, Pinnacles or other sites in the general area are likely to be affected by the fires in the North Bay? I have been observing at Lake Sonoma but right now I imagine that site is likely to be very affected by the terrible fires. Any thoughts about sites in the south? Thanks.

Great image!

This was only my third time, I gather this site has been used for quite some time. There is a road that goes by the lot so there are headlights that can be a problem. Sometimes people do drive into the lot, but last Saturday night no one except observers did so not a problem. It's a big lot which helps.

Observing Reports / Lake Sonoma 9/23/17

I observed at Lake Sonoma Lone Rock parking lot on Saturday 9/23. Conditions were much better than the previous week, with good transparency and a well defined Milky Way. A three day old crescent moon was not too obtrusive. There were about 5 or 6 observers including one imager. I set up my C8 next to my friends Ray's 18". I went through a list of globulars and galaxies, including NGC 6723 and attending nebulosity on the Sag/Corona Australis border which made a nice field. I also think I managed Barnard's Galaxy, as I found the Little Gem planetary, then eased south and a bit east to a milky patch elongated north/south. It was faint, but that's my story and I'm sticking to it.

Ray had Jones 1, an interesting planetary in Pegasus which showed nicely in an Orion UHC filter. I enjoyed edge-on galaxy NGC 6207 near M13 tonight, which I couldn't see in the haze last week. Through the 18", the "propeller" in M13 was clear but we couldn't see IC 4617, the other galaxy between M13 and NGC 6207, although I have seen it in a 25".

NGC 6939 and 6946, the open cluster and Fireworks galaxy pair in Cepheus, had me literally on my knees trying to look through the finder on my C8. I need a RACI finder for these northern objects! Finally got it, the galaxy big but amorphous, no sign of arms, the cluster very rich and reminding me of M11. In the 18" we did see indications of the spiral arms.

M55, M2, NGC 7814 and then M71 with its interesting shape reminding me of a tropical fish swimming through a sea of stars. Continuing the aquatic theme I went up to the nose of the dolphin, Gamma Delphini, ending the night on that beautiful double. A good night!

I'm planning to go Lake Sonoma Lone Rock parking tonight, looks like nice weather. So far looks like a 18" and a C8 coming.

I may have to get one of those, sounds good. I will say I have enjoyed the Veil with unfiltered 7x50 binoculars at a dark site, wonderful wide field view.

You are probably right, I'm thinking it must not have been an O-III filter, but I thought O-III showed the Veil best? I was impressed with the view.

I observed last night at Lone Rock parking lot at Lake Sonoma. There was a nice turnout, more than a dozen observers and some large scopes including two 20+" StarStructures. This was only my second time at Lake Sonoma, a few people said it was one of the largest gatherings they had seen in this location.

Compared to my first visit two months ago on July 24, transparency and darkness were noticeably worse, probably from residual smoke and haze from wildfires. The Milky Way lacked the clarity and richness I remember, but nevertheless I enjoyed hunting down a few new targets, mainly some globulars in Sagittarius I don't remember seeing before including NGCs 6638, 6528 and 6522 and revisiting favorites M28, M22, M2 and M15. NGC 7331, galaxy in Pegasus, was nicely shown in my C8 at 85x as elongated with a bright central area, but I didn't glimpse any of its companions. I had Barnard's Galaxy NGC 6822 on my list. I thought I glimpsed it with 7x50 binoculars, but couldn't confirm. I could not see it either with the C8 or a TeleVue 76 APO. It will have to await a better night I suppose.

Using my Lumicon O-III filter from back in the 90s, I saw the western portion of the Veil Nebula around 52 Cygni as beautiful "smoke" draping and rising from the star, but the view in my neighbor's 8" achromat of the eastern Veil also with filter was much better, and many more stars were visible. Do O-III filters degrade over time? Mine seemed too aggressive in blocking light.

My friend and I packed up as the Pleiades were rising. Even if transparency seemed a bit lacking, it was a wonderful night meeting some old friends and making new ones, both of the human and astronomical kind!

I'm planning to observe tomorrow, Saturday 9/16 at Lake Sonoma. I'm bringing a friend and believe there might be 5-10 others also planning to come, so I thought I would post here for anyone who might be interested. Hope to meet new observers!

Brad, nice report, and thank you for the heads-up about McDaniel Ranch. My friends went up there with their 9 year old son and had a wonderful experience.

My family saw it at Black Butte Ranch near Sisters. Smoke threatened all weekend but it cleared just for the eclipse morning. Incredible - we were closer to the edge than the centerline but  I saw the ruby-garnet chromosphere almost the whole totality.

Observing Reports / First time Lake Sonoma 7/24/17
« on: July 25, 2017, 01:52:33 PM »
Last night 7/24/17 I observed for the first time at Lake Sonoma, Lone Rock parking lot. A friend, also from SFAA, joined so we had two C8s plus a new Televue TV76. I enjoyed the site, much darker than Mt. Tam, Milky Way well visible and good horizons. Scorpius sprawled in the south, we could easily see under the tail. M22 was very nice in the Ethos 13mm, M51 showed spiral detail, I finally split Izar after having trouble with the seeing at my house in Mill Valley.
But the most fun was scanning the Milky Way with the TV76, a 24mm Panoptic gave a beautiful 3.2 degree field, the Lagoon and Trifid were set in a sparkling field, Antares and M4 likewise, the Swan Nebula stunning and swimming in star fields. No faint fuzzies hunting this night, unless you count the endless knots of luminosity in Sagittarius and Cygnus.
We had some dew starting around 11 pm and a handful of headlights. A fast colorful meteor from the zenith towards Polaris marked the end of my session around midnight. Hope to return often here!

And to clarify, we plan to meet at the Lone Rock parking lot.
