Last night, I was stuck unusually late at the Westport Observatory and managed to make my way into a back room, and found two scope cases that had not been opened in a long time. I was told nothing was in them. Out of curiosity, I opened them and I was greeted by a Meade 2080, two Meade drive correctors, and an orange C8.

 

Here it is the moment I opened the C8's case for the first time:

Since I already have a Wedgepod for the C5, I took home the C8. I have this scope till at least December. The 2080 has a tripod (albeit rusty) but I lacked space in the car last night for it.

 

The power cord was still sealed in its bag, as were the original Allen keys and accessories. This scope had never been used. Furthermore, it's got a green case and holes in the forks, making it a sandcast scope.

 

Judging by the serial number, it was made in the 3rd quarter of 1973.

I had to clean the corrector since it was foggy (common issue apparently), but other than that it's in amazing shape. It almost felt like a crime unwrapping everything!

 

First light tonight.

A "CLASSISC" and BRAND NEW - a real "time capsule" find ---- a Celestron  "collectors" item for sure.

Very nice! I love to look at pictures of old astronomical equipment from an era when quality--if not necessarily optical, at least mechanical--actually meant something. smile.gif

Some day I hope to look through one of those old scopes.

Looks great, really amazed you didnt see any fungus on the optics, sitting all those years. Great find...I hope you can get to make an offer on it, its sad to keep a beautiful instrument like that not getting any photons

You may have jewel there. Supposedly Robert Goff was the optician at Celestron at the time. He is said to be their best optician and I believe he’s the one Criterion tried to take away. I’ve been told a scope made by Mr Goff is as good as it gets. I would love to see a DPAC of that one. I know a 73 I had was superb. The guy who bought from me was so pleased he won’t sell it...unlike I didfrown.gif

 

That may be the best SCT you will ever look through....

It’s a lovely C8 Augustus. Hopefully they will let you keep it. I have a wedgepod like yours and Imfind it convenient and servicable. I also have the C8 wedge on a heavy duty Universal Astronomics wooden surveyors tripod, but my wedgepod is my favorite thing to use on my deck. Good luck and happy viewing.

I also have a  3rd quarter 1973 C8 bought second hand 2011 from a women here in Sweden who found it stored in an attic owned by her uncle who had passed away and not used it for many years. (It`s on the C8 registry.) The corrector was perfectly clean and I just love this scope. Very nice views and startest looks almost perfect. Eventually I wanted to use it on a "modern" eq mount so I have deforked it. Yeah i know it`s almost a crime but of course I have saved all the assecories so I can fork it again. Bought a dovtail from ScopeStuff and Bobs Knobs. Also a f/6.3 reducer. Everything works fine. I really enjoy this old beutifull C8. Of my scopes this is the one I use the most! I have no idea, but if Robert Goff is the man behind this C8 I would be more than happysmile.gif

Sorry I don`t know how to send picturesmad.gif

 

Best Regards,

Magnus

 

It also came with impressive green casewaytogo.gif

PS Thanks Augustus for your nice pictures of the -73 C8 and the story how you found it. I DO hope it will be yours permanently!

Any chance there will be a shootout with the Meade? My money would be on the Celestron, but......

 If your going to  do  a "shootout" get them both in front of an optical flat and show the double pass results. Then you have no bias in the results and there is no Celestron vs Meade war started or old C8's  and better then new C8's etc etc .  Your also going to possibly see problems that can be easily fixed and tell very quickly if you did fix them vs being  puzzled at what errors your seeing in a star test.

You may not like what you see. DPAC of a couple instruments that I thought were "good" showed they were just OK. I do have a C8 that looks decent under DPAC, Had others that were clearly lousy. A year or two ago I tested all my 80mm scopes in green light. One was good one was exceptional. The others were all MEH..  A 3.25" F15 Jaegers was very good accept for a glass( internal) defect on the edge. Winner was a Celestron Vixen Polaris C80, dead ruler straight lines. Another 80mm F11 was pretty good.

The master blank was still fresh in 1973. All the Meades before 1992 were not that great or i should say 9 out of 10.

Interesting I have pics of C80 DPAC with 1/2wave under correction...and I thought they were all great!

They would vary also.  Not as bad as SCT's since most seem to be good. But there is always a flunker that gets out of the factory.  Same for the Caves.  Seems only AP and a few others seem to get it right dwight time and time again.

Had an Orion Vixen 80mm that was about 1/2 wave undercorrected as well. The C80 I have is probably a good bit better than average. 1/2 wave is quite good for an SCT. 1 -1/2wave seems to be the norm most older SCT's. 1/2-1/4 Wave? Darn good. Better than 1/4 wave? Show me a real test report.

Augustus - Before the crowd manages to turn your new-found silk purse into a sow's ear, I for one would would love to read your first impressions of this C8's performance as compared to some of the other scopes with which you've had experience. I've read quite a few of your posts over the last few years and I tend to value your opinion.

That may be the best SCT you will ever look through....

 

I was just about to say the same thing. He may have an absolute Gem with that serial number since it's very likely that Goff did the secondary and corrector. I was informed by Celestron that Goff did my scope after sending the serial number to the right person. Bob Goff was Carl Zambuto's mentor. Mine is the best SCT I've ever looked through ever in fact Kevin at SkyWatcher stopped by to see Jupiter through it on his way through town and said.... what the heck is this! The optics are absolutely tack razor sharp. Jupiter snaps into focus with amazing surface detail with world class contrast. I guarantee this will stand up to the best 8" Maks or Mewlon's costing several thousand dollars in fact I wouldn't take $3000 for this SCT. What would I replace it with? One thing I learned in this life is when you find something this good, you don't ever let it go unless you absolutely have to. So far, I've not made those mistakes.  BTW, no fancy HD optics or XLT coatings. Bring it!

Hi all, very nice orange tubes you have there! I feel the same way about this scope. It’s a 1st quarter 1974 and has superb optics. At one time I was up to 23 mostly classic scopes, which have all come and gone and yet this one remains and is my primary scope. I will never part with it. It just does it all and does it well! Especially after adding the extension.
