Looking forward to seeing the pictures.  I can't help with the visual back as mine is a 1981 model.

This sat in the case for around 42 years. I will try to look it over this weekend and see if there is a date on the motors.

How about a serial number and specs like special coatings (I see the stickers), what came with it, it's history and any other info you think of interest.

 

I should talk, as I need to take some good photos of mine and provide info.

I just got it and need to look it over.  It has extra coatings as it has two stickers on the tube. I will see what all i can this weekend.

I don't see a date on the motors. SN number is # 3 2275 6. Has enhanced coatings.

I think the only thing missing is the .965" OD visual back and the correct wedge.  The factory power cord was never used and still wrapped in plastic. It had turned to dust and a new cord was used with the old female end.

My C5 turned out to be a winner.  Very sharp once collimated.

Looks like 3rd quarter of 1976 ?

Very pretty kit!  I keep my Questar in its case, but my C5 on its tabletop wedge are always on display.

I wanted to keep my C5 in the bedroom on the tv stand but it gets in the way of the TV.  I guess it could be one of the last small base C5's made as they went to the new style in 1977.

Gosh! that C5 looks brand new - looks a good find, Charles.  I also like the row of eyepieces you have set out.  Thanks for the serial number.
 
Thanks also for your details, Mike.

Odd, it's working at this end on both my tablet and a desktop that wasn't used for the post, I'll try the computer at work tomorrow and see what that does.

Fingers crossed and looking forward to some pics if it all works out.

I will have pics.  Any of you guys with the mid and early C5's have any problems using a newer 1.25" Visual back?

 

I have a C5 I  purchased fall of 1976.

 

Anyway, I did remember that the threads were slightly different on the C5 than the C8 from that time period. I suspect my scope was during the transition period. Hopefully, somebody else can get better information to you.

 

On mine, I have been able to thread different adapters (I think). I can check. The scope is up at the cabin....it will be interesting to see what "adapters' fit on it. I also have a Meade 8 inch SCT and plenty of adapters for that.

Mine are the same as the newer SCT's it seems.

Production date on the Synchron motors is on the cylindrical side, not at the flat round top (or bottom) where the name and patent numbers are. So it takes a bit of effort to spot the date om them.

Part 1

 

I've been meaning to register this one for awhile. It's the 1974 sand cast C5 that I looked at last August.

 

When I went to look at it, my enthusiasm for astronomy and telescopes turned out to be so contagious,

that the seller decide to keep it until he was ready to buy another scope.

I never thought I'd hear about it again so I took the opportunity to buy my brothers 1980 C5 on Sept. 27th (already registered).

Five days later, the '74 was back up on Craigslist!

It haunted me so even though I was about to leave town for several months, I left the seller a message.

 

During that time we had many friendly phone conversations (on all topics).

At some point he told me since I had been helpful with telescope information, he offered it to me for a price I couldn't refuse.

I told him I could pay him to hold it, but since he wasn't comfortable with that, he made the very kind gesture of delivering it to my wife.

 

I purchased it on November 17th and didn't see it until my return on January 10th. It was kind of a strange,

since I hadn't seen it since August 1st.

C5 Case .jpg

Until purchasing this scope, I didn't realize they ever came with this type of case.

C5s-In-Case.jpg

The whole package is much more compact than the later models' trunks.

Except for some small scuffs around the corrector's cell from the cover, it's in excellent condition.

Serial# 2 942 4

The seller's father picked it up from Celestron in June 1974

I could only make out one motor's date. Stamped 9/72

 

More to come

Part 2

 

The seller included his father's original paperwork.

C5-Order.jpg

The order date was April 12,1974. That's a lot of money back then.

The wedge and tripod are not listed on the paperwork. Perhaps purchased later?

 

C5-Letter.jpg

Letter dated June 7, 1974 from Celestron informing it's ready for pick up.

 

C5-Access.jpg

The original .965"accessories, except for the barlow, which the seller purchased NOS just before selling the scope.

It doesn't have the red allen wrench pouch. Perhaps it's before they were packaged that way.

 

C5sandWedge.jpg

Note the tilt plate is assembled upside down.

The seller kept the original sand-cast tripod since it's steadier for his C8, but included a die-cast tripod. 

 

C5-Manual.jpg

Can you believe this is the original instruction manual? I had no idea they were once so simply printed.

It reminds me of my 1978 Cave price list.

 

C5-Brochures.jpg

I assume these two product documents came together. Only the one page insert (left), has a date (7/73)

The one on the right is double folded to reveal three inside pages of information.

All of the photos but the color photo of the C14 are of the Tri-color versions.

 

This scope does not appear to have the optional special coatings.

There is no sticker on the OTA or mention of it on invoice.

I still need to test it and see how it compares with my 1980 C5 that does.
