My lovely Assistant Astronomy found this one for me.

 

Celestron Pacific Celetron 8.

 

This must be a very early scope.   The effective focal length, rather than being stated in millimeters, is stated as "80 in."

 

From 1975 I think? 

 

The tripod was trash (had been left outside for maybe a couple of decades) but the OTA is actually in nice condition.   The optics appear to be clouded up, and maybe the coatings have tarnished.  I don't know.   I will take the corrector off today and clean it up.

 

It is such a handsome little telescope though.. I remember admiring the Celetsron ads in the back of the astronomy magazine long ago.  They just seemed so "Modern". 

 

Just thought I would share.

Wow, same year and model as my first C8.  Bought it new for $800 in 1975 from Optics b/c in Oakland, CA.  

 

I guess that would be a lot more money today !  Love those sand cast forks with the holes through.

Sweet!  I still have and use mine regularly.  I did have mine recoated by Celestron back around 2002 with Starbright since I had some areas of coating loss on the edge of the primary and the optics are really well corrected.

Thanks all.

 

Cleaning was a total success.   The corrector was very difficult to remove.  I had to use a combination of pressure inside the tube, (and I know this will sound crude, but if done carefully can work well) a plunger on the corrector, and a lot of heat on the cell.  The foam gasket had kind of stuck to the corrector, but when I applied heat, the corrector did pop free without doing any damage to the foam gasket. 

I also pulled the primary.  

 

 

All surfaces had some buildup on them but a good soaking to loosen it and careful cleaning with my fingers got it all off.  Coatings look excellent (though I would guess they have lost some reflective by now).

The seller did not have a power cord.  I am not sure what to do about that because it is an odd plug.

 

I doubt that I will keep it (I am not into vintage stuff anymore) but It was a good price and worst case, I can probably make a little money turning it around.

Also some notes.

First, there was zero sign of grease on the baffle.  Zero.   Was it common practice that they did not grease them back then?  Perhaps the tolerances were a bit better.  I don't know.  The fit though was excellent.  I could detect no play at all, but of course I will have to use it under the stars to see if there is any shift.  I did not apply grease.  It had none when I opened it, and if it was shipped that way, that is they way I wanted it to stay.

 

The focuser is quite a bit different than later models.  It seemed to have more machined parts and very fine threads on the focuser rod.  Finer than I remember on my last C8, though my memory on this might be poor.  There was sign of lubricant here, so I did apply a super light coat of superlube.

 

The original diagonal is kind of simple, but it was included, but no eyepieces.  I did clean the diagonal, and if I sell it of course I will include it.  

 

It is a lovely little telescope. 

 

I may try to re-rehabilitate the tripod.  The legs are super-rusty, so I would have to find new tubing, but I will check with my metal supply.

 

It would be fun to get it back as close as possible to original, but again, I am not that into vintage stuff anymore.  With some work to the tripod though, it could be a very fun scope, though again, I would almost for sure sell it.

 

Most likely though, I will just sell the scope and wedge as it is now though.

Keep an eye on the classifieds for the C8 plug.

The older tripods pop up a few times a year so maybe just buy one when they pop up.

Yeah, I saw one that sold a while back.

 

The problem with tripods is that shipping is very expensive.   I am going to go to my local metal supply this week and see if they stock a tube that would work.   Long shot, but I think worth doing.
