Just recently acquired a classic C14 Compustar Telescope. not sure the color of the tube yet since it has a shield over the  heater covering the entire tube. 

Also has Sky Vector rings and encoders installed. The Minnesota Astronomical Society has been awesome and was able to also find the Y2K chip that belong

to this scope. I was able to get the chip installed tonight, the Compustar is good to go for another 79 years.

Wow, that's an exciting classic to get! I hope I get to see one someday.

Awesome scope! The light grasp makes a big difference. M57, for example, has a solidity that smaller apertures don’t present. The Compustar can be a power hog, so use a good size battery when running off the grid.  It also needs really good collimation to get the best results.

Yep, great scope, though very heavy, due to solid structure they tend to have being built in the hey day. I have the cousin brother unit that being, Classic Celestron 14in (orange tube),but boy what i bear to setup, and I setup and break down a 28inch scope literally just about every night thru out the entire year, and is much easiler for me to do.

Interesting though as a side note, I notice there is no writing on the inside corrector plate, for the specs of the scope, F-ratio, size, etc.. most scopes normally have it.?? Is there any writing on the tube assembly to convey which company made it? I of course see the celestron logo on the motor drive, but more interested in any logo on the tube assembly itself, back plate etc. Just curious.

By the looks of the 2 ndary cover it could be a older Orange tube.

Well I carefully removed the silver metal cover from over the heating element just to  enough to expose tube color.

With some help from my wife fixed a flexible tube to the vacuum and managed to remove a cob web from just behind the collector.

Took the measurements so I can build a cart to mount the tripod onto.

Oh the Tube color is Black, didn't uncover enough to check out any other markings. When I tear it down to move it outside I will get the numbers from the fork arms from the build.

Clamchip (Robert) will probably be along with a picture of how he mounted his to a rolling dolly from a big box store. As I recall, it could raise up enough for seated viewing, and he bolted the wedge directly to its table, without using the tripod. The advantage was that he could wheel it out of a normal door.

I saw a post about it being on a Harbor Freight Hydraulic table, Looked like an good idea.

Yes it works great, well enough to go through my shop door in one piece.

I found it stable and I liked the ability to observe seated and hydraulically

put the eyepiece in the most comfy place.

Talking about it brings tears because I no longer own the C14 and the orange

table went with it.bawling.gif

I originally bought the Harbor Freight Hydraulic Table for moving around and

working on antique gasoline hit and miss farm engines.

Great find.  Here is mine, which is the only Orange Tube Compustar C14 that I know of in existence. Oddly enough, it has the Starbright Coatings too which weren't too common on the orange tubes.

Great looking C14.  Found the Compustar Users Group now.

Its always fun to discover other interests in common.  My summers are always occupied with antique machinery shows (hit & miss, steam. Stirling, etc).

Ok during tear down today in getting it ready to move up the stairs and out to the garage the numbers etched into the forks are 2047. 

So not sure what it really means other than fork and base 2047 produced for the Black Tube C14 Fork Mount. When I had the Compustar open to install

the Y2K Chip there wasn't even a born on date tape like I have seen on others. The only interesting thing I have noticed is the pristine user guide is dated

September 1985, so 1st version. 

Hopefully my Scope Buggy shows up soon since we will be getting above zero for the next few days.

I've been thinking about getting one of these for Cosmic Acres to use to help hoist heavy/bulky OTAs up onto the mount (and perhaps other things).  But I have a question:  When you turn the handle to let the table down, is it possible to have it go too fast?  Like a floor jack that you release suddenly?  I wouldn't want to damage anything by having it crash down. Also, if one could raise and lower things slowly, something like this might make a suitable pier base for an adjustable height pier, if it were securely bolted down (with wheels removed, for example).

You can lower it slow or fast or anything in between because it's a valve that releases the

fluid from the cylinder, if you just crack it open it will take hours to lower.

And you can raise it slow or fast too with the jacking handle, by foot or hand.

The cylinder will blead out though, it takes a few days and the platform will be all the way

to the floor.

Doesn't sound like a safe option, then.

I wouldn't want to use it as a pier because there is quite a bit of wiggle in the

working mechanism of the table.

The hydraulic lowering and raising is predictable and safe, although there is

a element of danger, say if the release valve gets opened too much by accident.

It works exactly like a standard bottle jack.

Didn't the wiggle interfere with how you used it?

Not with the weight of the C14, this kept all the table hinge pins and scissor bars

and everything tight. I had no problems, with damping times zero even at high power.

It worked extremely well. If anything there was a little sway, if you gave it a shove it

would move, give it a push and it probably would have toppled over and I would be

responsible for destroying a National Treasure. I didn't know just how much of a push

but I sensed it would not have been much with the table at full height.

I also owned the tripod for the C14 and it was far better and completely without fear

to use. The hydraulic table you needed to pay attention when using like always lower

before moving the unit, and not to open the valve too much when lowering, etc.

Faced with the choice of using the hydraulic table and out my shop doorway and

observing in 5 minutes, or unforking the optical tube and reforking every time I wanted

to use the scope, I chose the former.

I forgot something else handy about the hydro table, unforking and reforking the OTA.

Rather than man-handling the 50 lb telescope into the fork I would set the optical tube

on my work bench corrector down and bring the table with fork up to the tube and

precisely dock with it, really nice. 50 lbs doesn't seem like much but when its a scope

and not a bale of hay it feels very heavy.
