This may have been put in solar system observing, but since I will be bragging on my (new to me) vintage C-80, I will put it here. I received this scope several days ago, time capsule condition, everything just like from the factory. I know that Mars is getting very small now, and detail is getting hard to see. But being a clear and warm day in NC, I decided to try my first light on Mars, and even though it is getting smaller, I could see a dark area all the way across the center, and then a dark area spreading down from that. With the 7mm ortho, I was really surprised at the detail I saw. These little scopes are really impressive, I would not be afraid to say about one of the best 80 achros ever made for the money. I really wish Jupiter and Saturn were out now, but I guess I will have to wait til next year. Saturn is now below the tree line when it gets dark enough to view. I may try Venus in the morning, but it is turning colder through the night.

I have had a few of these scopes and all were super sharp.

The one I had was sharp, sharp, sharp! The only reason I let it go was that my FC76 could best it and was smaller.

I too had one (bought new when first introduced) - was pretty good for a 80 achro--- moved up to a C102F which was VERY good.

I've had a few only one was not so good with 1/2wave under corrections. Got A DPAC of that one. I was a bit surprised. Never bought another one after a Vixen 80mm fluorite ruined it for everyone else.

Very nice pick up....hard to find stuff in barely used condition

  I have the c-80 firstscope in ok condition for  a craigslist rescue I got for for peanuts  but optically it is very good

I have the big brother c-102 

 

Have to agree with Rolo    my new to me Vixen 80mm fluorite steals the show and has my attention all night long....

 

enjoy     love to see some pics

Congrats on your new scope, Billy!  I've heard good things about the C80, though I've never looked through one myself.  Have fun out there and stay warm. smile.png

Ditto. I currently have two, one on the Polaris mount, and one on an Alt/Az.

I’m a new owner of a C80 too. I haven’t had a chance to put it to use yet, it’s pretty far from time capsule condition. I’m in the process of acquiring a few extra parts to get it up to the challenge. I’m excited!

Billy, congratulations! I have a feeling you are really going to enjoy this scope. It’s a real keeper in my estimation! ;)

What was your percentage of the products you mixed for wood conditioning?

Good scope, I have a Polaris C80 and it is a VERY good scope. DPAC was very very good. Sent most of my 60mm scopes packing.

It was about half and half of each.

Was the C80 a orange tube with collimated lens cell? Never had one but had a CB-80 + Premium 80. Both Celestron/Vixen on beautiful wooden altazimuth mounts. Purchased both locally for $120 each. Very nice scopes but each at various years owned....didn't do any better than a 70mm x 900mm Celestron Firstscope China made in side by side comparisons. The 70mm beat both scopes with less CA using Japan and Taiwan made eyepieces. I felt I could split the double/double in Lyra at little less power with the 70mm's. Probably because less glare in the smaller objective with longer focal length even though each scope in the 900mm--910mm focal length range. Was it just me or did I expect more from a 80mm over a 70mm? Those Celestron/Vixen wooden legs were just beautiful. I've read they were made from Teakwood. Very sturdy with no vibrations with the altazimuth mount. I kinda wished I had the orange tube on the wooden tripod legs.

Interesting that your 70mm beat the 80mm. The 70mm is f/12.8 vs. 11.4 for the 80. Perhaps that’s the reason there was less CA?

An older (adjustable-stalk finder) C-80 was one of my best scopes, replaced with a 77mm Swift, which is both more vintagey-cool, and more importantly, now has its second objective in it, and is an even better performer than the C-80 - but not by much.....

 

I'd put the C-80's, on a Polaris mount, as being the best affordable mid-sized achromat out there.

My brothers new-in-1987 Celestron SP-C80 is still awesome and I also love my Vixen 90mm refractor. These things are a great blend of classic and modern and they are so easy to set up when bigger scopes would be too much of a hassle. Thomas

Thanks to all of you who have congragulated me on my C-80 scope. It is nice to know that so many of you also love this scope. Especially as I get older, the simplicity and light weight of this scope is a real plus for me, and the optics show me all that I need to see, and probably as much as some scopes that cost much more. It is kind of sad that Celestron stop making such a good scope, or just as bad sending the manufacturing to China. As I look back in some of my older catalogs, and read about these scopes when they were new, some of the reviews tell about this scope being the best seller in many countries. Even the 1985 catalog from Orion, they say that this scope is their favorite of all the scopes they sell.

But as aperture fever swept over the country, I guess many wanted to be able to see more, when in reality, seeing more is sometimes not worth the hassle of moving huge heavy monsters around. And to be truthful, some other larger scopes that I have used, showed no better than this scope has shown me.

I guess I have been on my soap box long enough, just happy to see that some of you love these scopes too.

Here's something you don't see every day. Back in 12/2005I took this image with a C80 a Nikon D70 and an unguided 30 second exposure at ISO 1600.

The moon was with the same scope and camera at ISO 200

That's was an SP C80 unguided on the SP mount with a nice drift alignment.
