 Hi all:

 

Some time back, I came across one of the older orange Celestron C8s. I'm guessing it was made in the early 1980s. I have spent the last few years replacing a few parts, and finding a few others, and am close to having it ready to use. The OTA seems to be in good condition, and the mirrors have the Starbright coatings. Just to be sure everything was OK, I sent it to Celestron. Their initial evaluation was all the C8 needs is cleaned and laser collimation.

 

I plan on keeping the C8 long term, even if I procure another telescope a few years down the road. So the question is, while it is at Celestron, should I consider having the original mirrors recoated? If it were your telescope and you were planning on keeping it for a long time, is there anything else you would want Celestron to check out or replace while they have it?

 

Thanks,

Gene

 Only if they need  newcoatings. What does Celestron recommend?

Personally I would leave it alone. My ‘78 performs very nearly as well as my 8SE. A side by side test is the only way to tell. I’m very happy with the performance of my classic! Of course that depends on the condition of the coatings. They are approaching 40 years. I would consider cost as well. It is already in their hands. As for other things, how about lubing the focus? I hope you have many years with it! Clear and steady skies.....

I have never seen a Super C8+ with orange OTA but I suppose it is possible.  They do have a rather nice Beyers worm drive, RACI finder, and robust tripod.  If I were sending mine to Celestron I would have them evaluate the coatings, have them tighten/adjust/lube the focusing mechanism to minimize mirror shift, and have it cleaned, collimated, and tested to confirm it's 1/4 wave or better performance.

That's my thought as well.   The marketing stuff for the original (non-plus) Super C8 shows the scope in black, and marks the start of the black tube era (released mid year of 1983)..  Nonetheless, Celestron definitely shipped some orange Supers.   However, I would think the supply of NOS orange OTAs would have been exhausted by the release of the Super C8+.   If a Super C8+ mount has an orange tube OTA on it, I'd suspect a tube swap as much more likely than it coming from the factory that way.  

 

At any rate, it CAN"T be early 80s and a Super C8+, as the plus model wasn't released until 85.

No.  They first came out before black replaced the orange.  There was a miss match and old stock left over from around Jan 84 to 85.  It was a mix of both it seems.

On Page 17 of "Uncle Rod's Used CAT Buyer's Guide" (   https://skywatch.bra...ed/used_sct.pdf ), the Celestron advertisement shows an orange-tubed Super C8.

No, it does not.  

 

The Super C8 is the black scope in the foreground.  The orange tube scope is the standard C8  the Super C8 "superseded."  I can understand the confusion, given the location of the "Introducing the New Super C8" text, but the orange scope is the old model, with its 6x30mm finderscope and the older-style tripod.     If you read down on page 17, Rod states that the on Super C8 "the dinky 30mm finder scope was gone, replaced by a nice 8x50 model equipped with a star diagonal for comfortable viewing."   Note that only the black scope has this larger, right-angle finderscope.

But the Super C8+ did not come out until 85.   There were definitely orange Super C8s, and I suppose it's possible that a couple of of NOS orangetubes made it to the start of the C8+, but Celestron marketing clearly intended the Super to be black from it's introduction (as in the July '83 ad referenced above).

Correct.

 

Ive definitively seen OT Super C8s.  Never an OT Super C8+.  To my knowledge, Celestron never offered it.

I have a Super C8 (I think the Super means it has the Byers drive) that is Orange.  I am guessing the + means special coatings?

 

 

To the OP: if the cost isn't too bad, I would have them recoat just because it is there and disassembled.  It's over 30 years old so it is a matter of time until they start to go bad.

No, the Super C8+ replaced the Super C8 in Celestron's line-up in 1985 [or perhaps 84].  The two scopes are very similar.

 

Both had the Byers drive.  The Plus has a somewhat beefier fork design with different setting circles, and an improved finder bracket.  It also came with Starbright coatings as standard, but they were also available as an extra-cost option for the (non-Plus) Super.

 

 

[Note:  I originally typo'd 1995 instead of 1985 above.  I corrected the typo to show my original intent.  Also, based on advertising presented later in the thread, Super C8+ ads started occurring in 1984, so perhaps the reign of the non-plus model was even shorter than I thought.   This would increase the possibility of orange tube Super C8+ scopes.]

Here are the ads from S&T: The Super C8+ has been advertised since June 1984.

Then add in all the Meade SCT's over the years and the flops like the GEM in 1987 and them ugly fork mount models on a pier around 1990.

Oops.   That was a typo.

I'll correct.

Celestron really went down hill after 1995 with that cheap made Celestar and dumbed down fork mounts and base.

Thanks for answering a question that you didn't even know that I had Robert.  lol.gif   I wondered if someone had repainted the OTA on my SP-C8 because it didn't have the orange Celestron name on it.  Going by the Aug-Nov '83 ad, it looks like they left the name off it.

Thanks for all the information. I am going to touch base with Celestron to clean/adjust/lube the focuser, and am going to have them evaluate the coatings and test for 1/4 wave or better performance.

 

After reading through everyone's comments, I was probably incorrect in stating the telescope was a Super C8+. It is an orange tube, with an orange, right angle illuminated 8x50 Polaris finder, camera mount, Buyers drive, heavier tripod, and Starbright coatings. Also, I thought that only the Super C8+ scopes had the window cut out in the Buyers drive - which mine has ( Uncle Rod’s Used CAT Buyer’s Guide 17). However, the setting circles are definitely those found on a Super C8 - not a Super C8+.

What's the Serial number?  Mine is in the 819***.  You should add it to the C8 registry. Good Luck!

The wedgepod was not one of their better ideas, that's for sure. 

 

On plus side, optical quality tends to be pretty good on the Celestars.

That's what I always thought was the clear determining factor.

I bought my Super C8 plus in the spring of 1984, was told it was was one of the first 50 produced. Sunwest Space systems in St Petersburg ordered a bunch of them at once but I ended up with a demo model that Celestron sent to Ronnie Beck before the ads even came out. We set up over half a dozen and star tested them. The demo was the clear winner, the rest were all over the place from fair to bad.

 

The demo had "good optics" but nothing special for sure. I kept that scope for several years until I bought a 12.5" f6 newtonian. It traveled a lot of miles, TSP, Astrofest etc several times. Never missed it though once it was gone.....
