Mt Pinos is Open!

Last night at Pinos(Saturday Oct 21) was awesome!
The road was re-opened by the forest service on the preceding day, just in time for the Orion meteor shower.
There was only one other amateur up there when I arrived in the afternoon but, by nightfall, at least 30 other scopes filled the parking lot.
It was refractor city up there with TAK APOs dominating the group. Several TAKs and two TMBs were represented in the 5" and 6" sizes, with several on massive mounts.
Despite the arrival of the hunting season, no disruptive effects occurred during the night although a couple of hikers managed to get themselves lost on a cliff but they were spotted by a search and rescue helicopter before nightfall and were rescued.
There was traffic from people coming to view the Orion meteor shower but they left after midnight and things calmed down.
Now to the good stuff: transparency and seing were great with no wind and a temperature of 32 degrees F. The most spectacular object of the evening had to be NGC 253 in Sculptor. It was incredible! It filled the eyepiece of my 65 AFOV pentax xl 10.5mm eyepiece in my 16" dob, from one edge of the field to the other. One of the TAK observers viewed it through my scope and couldn't believe it. This galaxy has to be seen to believed. It's said to be the apparent size of the full moon in the sky and it's immense: even though it's 11,000 light years away, it was reported by a TAK observer to be 80,000 light years in diameter and Astronomy magazine claims it can be seen visually at a dark site when it's riding high in the sky at a magnitude of 7.6!
I viewed a host of other galaxies in Perseus, Pegasus and Aries. Finally, Oren Soffer and Richard Spina invited me to view the blue snowball planetary in their 17" F 4.1 DOB at, get this, 1800 power. That's not a misprint, Oren used a 2.3mm eyepiece with a powermate and achieved a phenomenal amount of magnification and the object took it!
Both Oren and Richard shared great views of the horsehead nebula while I also observed Stephan's Quintet with the dimmest member at 15 magnitude being easy prey in my 16" dob.
I'm thinking of going up again during the week...

Hi Rod,
Wow, it was 28 degrees at Lockwood Valley 3,000 feet below you. I guess the Santa Ana Winds must have made it warmer up above? Strange. :S
We had a good night at the LAAS site with about 20 people present and everything from Refractors to Off-axis reflectors there.
Glad to hear that all went well at MT Pinos.

Thanks for the report, Rod.
NGC 253 was indeed looking great.
I assume you meant 11 million light years distant,
though I show it as 8 million l.y. in the NSO guide.
I didn't realize the Sculptor Group is closer than the M81 Group.
Despite all the fine DSO's though, I think I'll remember the night
by a great view of Comet Swan and the excellent Orionid meteors.
I sacked out at 3:00, watching the meteors streak across the sky, straight overhead. grin

It sure was a great observing night, maybe to compensate for the bad weather we experienced during the last year. I've never seen the Blue Snowball with so much details, it seemed like more power was making the object bigger with more details visible, but it didn't make it much dimmer to my surprise. I guess the contrast gain with higher magnification compensated for the larger image brightness reduction. A small correction, the two TMB's we brought were 152 and 175. The Dob was 17.5".

oren.
