First, nice scope.

Yes, I was talking about the clock on the radio. I had no idea parts were still out there. Cool. Mine still runs when I plug it in. With the Art Deco look I assumed it was from the 20-30's era.

Thanks Jim, The model name is "Jefferson Golden Hour", with a radium dial and heavy 24k gold plate over zinc on my early one. Over two million were made starting from 1949 until 1991 so I have no idea what one is worth. It's called a mystery clock because the hands float on a crystal dial with no apparent way to make them move. I'm into windup clocks but this was the exception as it was my Dad's.

That is a nice clock. I have the Spilhous space clock which is also a very interesting clock.

I love those space clocks. I'm looking for a nice wind up Sidereal pendulum clock but they are really rare birds. You can adjust a regular mechanical one to a Siderial rate but there were purpose made ones for observatories. U 0f SC's Melton observatory has one as I recall. Digital ones are available but they and the software screen ones lack interest for me.

They pop up once in a while on Ebay. Have never seen them anywhere else. I think only 2000 were made.

Yes , my 10 inch f/10 is almost the best Luna/Planetry scope I have ever looked thru , 25mm secondary disappears.
Here she is , the 2 parts of 12 inch aliminium tube in Dob form , each about 50 inches long as the f/l is 100 inches (2500mm )
But woaw you want to see jupiter in this .
Brian.

8"f12 would be awesome.
I've been experimenting with the 6"f13, mostly diagonal mirror size and the support for it.
The performance from these long newts is pretty much untouchable if you can control the tubes currents and all the other misc. thermal management of the optical tube.
They are a specialized scope and only good for high power but are excellent for doing just that.

Wow neat. Almost the best? what was the best?
I like the skeletonized tube. Does that help out with the tube currents or help with balancing the 100 inch focal length, I like that idea.
What's the gold truss scope?

Managed to get a better picture this time... same CI-700 mount but this time with the Towa #339 80mm/1200mm (Selsi branded). I need to mount the original clamshell ring on a dovetail as those ADM guide-scope rings have a more permeant usage in my imaging setup.

Here's a beat up 1950's Edmunds refractor; the 4 inch F15. Original objective, but the focuser is a replacement -- the original one was stripped and corroded.

Plus a telrad and lots of electrical tape.

It's on a EQ6 -- much more stable than the original mount!

Just switched the original Polaris mount for my 1984 Star 140 (Celestron Comet Catcher) for a new GoTo iOptron SmartEq mount. The GoTo might be great for finding object, but I really do miss how the scope looked looked on Polaris mount! I guess older ... sometimes ... is just better!

In reality probably not to far from one another off the assembly line. One of the first C-8's on one of the last C5- ASGT's.

Charles I thought Serial #01 was on display at Celestron headquarters as a gift from someone. Or do I have something mixed up here? Set me straight. Thanks. Mike ;)

I think it is on display, and it was formerly Charles' scope. However, it's OTA serial 01, but it's not the first orange tube. My Serial #135 "Tinky" is earlier than the Serial #1 OTA.

Tim is correct. The 01 was my scope...now displayed in the Torrance lobby...and yes, mine was the first Celestron sold as an OTA-only. While it's true that the production of Tim's pre-dates mine, mine has that cool "01" serial number plate :bow:
