Yet another Saturday night at Dino. This is for November 18.
I'm a gatekeeper -- I will stay until midnight, weather permitting, maybe later.

Our answer has always been no. There are plenty of observing websites spread out all over the map. The advantage of TAC is that it's local. Please don't. And Matt, it's different right up front when a local goes traveling.

So long as it doesn't get "out of hand" and become a world-wide astronomy board,
or suddenly generate spam, I see no problem with it.  An occasional observation
from far places is not unknown here, when one of the usual suspects goes on a trip
to, say, Australia.

I've been getting more and more signups from folks far out of the area.  latest one has a .in (india?) email and a .uk IP address, but filled in the 'scope' and 'interests' fields with reasonable values...

what think you all, should we open this group up to wider area participation?      It *is* quite possible they intend to visit here, etcetc.

TAC Astro Classifieds / For Sale: New TPO 6" f/9 Ritchey-Chretien Astrograph $295
« Last post by DrAl on November 14, 2017, 03:43:23 PM »
At the recent Advanced Imaging Conference (AIC) in San Jose, I won a raffle prize of a TPO 6" f/9 Ritchey-Chretien Astrograph with 2" focuser donated by OPT in Oceanside, CA.  As I already have many astrographs, I am selling this brand new astrograph at $295, a substantial discount. The optical tube is still sealed in its plastic bag!  The specifications for the system are:
Aperture           152 mm (6")
Focal Length     1370mm
Focal Ratio        f/9
Focuser              Design Crayford
Focuser Size      2"
Manual Focusing
Manufacturer      TPO   (Taiwan)
Optical Design     Ritchey Chretien
Back Focus from focuser:  150mm

This could be a good starter astrograph for imaging at this price.

For more information, see the OPT website on this astrograph:
If interested or would like to discuss the astrograph, please email me at

A high-quality hardcover book with ten night photography masterclasses, each written by a world-class, award-winning astrophotographer.

Check out the link to the Kickstarter Campaign:

And of course Rogelio Bernal is one of the ten award-winning astrophotographers.

I pledged and am looking forward to receiving a hard copy of the book.

All fine objects to be sure.    Glad it worked fairly well.   Having other plans I was unable to join in but till another time, Clear Skies Jamie.

Oh and on the way home I also did something I hadn’t done in a while, hit Casa de Restaurant for some pie. There was this one night years ago when Elena and Craig and Crilly and I hit what was then Casa de Coffee on the way home from Dinosaur Point. 3 of us had pie according to plan. Jeff ordered a full breakfast at 3 am. The reason he did this was that nobody could tell him he couldn’t. He polished it off, too.

Tonight, Saturday the 11th, I had Dinosaur Point to myself, not by design. Was fun though. This past year I’ve had several solo nights at the Pinnacles, but it’d been a stretch since I had a night alone at Dino. Conditions were fine for a winter night. There was some high cirrus coming and going, but at any time there were big swaths of clear sky, much bigger than suckerholes. For the better part of an hour, ca 9-10 pm, the whole sky was open.

For a change, I took along my 10x50 Orion Ultraview binocs with tripod and parallelogram mount. Had a big ole time picking up Messiers and bright NGC’s - galaxies and open clusters and globulars oh my.

253, the Sculptor Galaxy, took the cake. Stunning, went back and looked twice. It showed big and bright and long and detailed; could see the taper on one end and the stubby other end.

I’d looked at M31, yes the Andromeda Galaxy, a bunch of times in binocs and finderscopes, but had never till tonight picked up its close satellites. M110 jumped out. M32, which for me is the easier one in a scope, took some time to tease out of M31’s outer halo. That was fun.

M34 in Perseus and ngc 752 in Triangulum are spangly and pretty in binoculars.

Around 7:15 there was this one bright slow shooter below the Water Jar that went for over 30 degress. It’s still moving across the old retinas.

Paused at one point while looking at M33 and wondered who lives there. People on a planet around a star in that galaxy would have two big fancy naked-eye spirals in their sky, and 5 mondo emission nebulae, star factories, that we can easily see from here, 2.4 million lightyears away.

The air stayed dry, it was cold without being blistering. Did a starcount when Pegasus was overhead, got 10 stars for 6.2 limiting magnitude.
Fun night.
