Also, IIRC recently someone (in another thread?) mentioned one of those rear glass elements and it was said to be a type of filter. 

Any keywords I should look for? I'm not seeing it anywhere. You can see it mounted on the back of the scope here before the visual back. Doesn't appear to be any color and no markings/writing on it anywhere.

Found it.

Since it's a couple of years old there must have been a recent link to this topic. 

In post #7 Robert put a link to a 1998 Celestron catalog and they featured it on page 17

Probably early 1979. Mine came directly off the production line by a Celestron employee in mid March 1979 and is 800783. a

Wouldn't the 8XXXXX numbers be for a C8?

For the record - the posts of those numbers do appear to belong in the C8 thread, as Kasmos cites his own C8's registered number - 800783.

 

However, it is important to know that the C5 registry contains two examples in the 880xxx range. Thus such misplaced exchanges can be difficult to detect for the casual onlooker.

 

Good catch -

 

Your photo is of a C5.

Maybe randallpatrickc and the others also got their wires (C5-C8) crossed?

Purchased this little gem for $200 a month ago. Serial #53179. I am curious as to how to go about mounting it to a GEM or tripod.

The ota is easy to remove, there is one thumbscrew to loosen the dovetail clamp, and you have to remove a thumbscrew from one end of the dovetail itself. The dovetail is a vixen type, and even has a couple of threaded holes on the bottom- 1/4x20 for tripods.

From a comment on my FaceBook post about my C8's serial number. Scroll down, last comment on the post as of 2021-12-07 15:00 EST

 

"I own (purchased 2nd hand) a "Celestron Pacific" 5.5-inch Schmidt Camera - serial number 007 -- yep, number seven! -- from the days of the predecessor company, Celestron Pacific! It was re-manufactured by a company named "Epic" -- which for about a dozen years bought old Celestron 5.5 and 8" Schmidt Cameras, replaced a few parts - mostly with the film and filter holder unit, cleaned, painted if needed, re-assembled, collimated (not an easy task with a Schmidt Camera) - they came out better than new. I keep thinking I should either run some film thru it, or sell it to a collector."

I have a Celestron 750mm f/6 telephoto lens (acquired a couple of years back from another collector). I think it is a C5 (125mm f/6) model. The corrector lens holder doesnt show any serial number. The serial number is printed on the aluminium tape wound around the back plate of the lens.

 

I could only read the first 3 numbers correctly, but I guess the S/N is 7253 (made in USA). The primary mirror looks clean and shiny and so does the corrector plate and secondary mirror. I put a visual back and 1.25inch diagaonal and a eye piece and it focused well, the stars were sharp and round. the out of focus discs look like collimation is fine. the exteriors of the lens do need some work to make it look better.

 

Could you please help find what year this may have been manufactured. It is certainly pre "made in china" years.
