Hi all, a gentleman  came into our shop the other day for some repair work on his Jeep, anyway we got to talking and he's cleaning out his garage at home and came across his old Meade 10" SCT and wonder what it might be worth, he just said it was old.

 

I stopped by his place to take a look at it and there are no indications, no "LX" no nothing, just has Meade 10" Cassigrin on the box, it's still in the original box, he has only old plossels and a JMI accessory, the key pad is basic, should have taken pictures but light was not good in the back of his garage, the tripod weighs almost as much as the scope, figuring around 50lbs. The scope had to be near 70lbs.

 

He couldn't remember how long ago he purchased it, and to get a slight idea of value I'd at least like to know how old it is, the scope is used but in very nice condition.

 

Any idea's?

It's probably an LX10 or LX50 or simliar.  Value is probably in the neighborhood of $500-$600 give or take, perhaps a bit more if it's parted out.  Condition of the OTA (coatings, mirrors, mechanics) will play a big part as many people would likely only be interested in the OTA, itself.

 

If it's a f/6.3 OTA, that could add to the value.

 

With the availability of goto mounts today, the old RA drive systems are not as highly sought after as they once were.

What you're describing sounds like the original 10" SCT that went by the designation 2120 and was introduced in 1982. It was not designed for use with a controller though. You state that a "key pad is basic", so that sounds like the LX3 that came out in 1985. Either way the condition will carry more weight on value than which model it is. Probably less than $500.

You might have run across the "classic" Meade LX200, which came in a 10" diameter.  If you open the box and see the lettering EMC along the optical tube then it's a classic.  They came in f/10 only.  Depending upon condition and functionality of the electronics, it could be worth $800 for a motivated buyer.  The 90's models were made in the US, had no plastic or foreign made parts and were assembled in Irvine, CA.  I still have my classic LX200 10" OTA in my stable and is a fantastic planet killer.

would a serial number help?

 

I'm going to ask the guy today if I can take it home and work with it and maybe figure out how and what might be a valuable vintage unit, and this guy is old and he purchased it from another guy way back when,,,,,,,,,

 

the Orion plossl's might be kinda cool to have around.

 

There's a 2" 50mm

No, but a photo would nail it.

It might! I have been cataloguing Meade LX serials numbers for a while and I have a decent number of 10" serials - so I might be able to give you an indication of the year of the scope. But as randcpoll says above - a photo of the scope would be best. Especially the drive base where the control panel is - and the hand controller.

Again, a picture would be helpful.

 

I'm with randcpoll, and a bit curious...   A simple hand controller sounds like an LX3, but an LX3 drive would say "Meade LX Quartz Drive" on it.  No LX sounds like an early basic 2120 (is it an AC powered drive?), but that wouldn't have a handcontroller (unless it comes with a drive controller that has one).

 

So my best guess is an early 2120 with a drive controller.  But I'm probably  missing something.  However, if I'm correct, that narrows down the vintage considerably, as I don't believe the 2120 was shipping until 1983 and was replaced by the LX3 in 1985.

 

LX5, LX6 and Premier should all say "Microprocessor Controlled LX Quartz Drive" or some variant thereof.

 

I don't think there was a 10" LX10.

 

LX50 drives are labeled as such, as are the LX200 models.

 

Meade did reintroduce a simple vanilla 2080 in the early 90s as their answer to Celestron's back-to-basics Classic 8.  I don't think there was a matching 2120, though, but I could be wrong.   If there was one, it wasn't mentioned in Uncle Rod's SCT guide (unless I missed it).

 

 

You might have run across the "classic" Meade LX200, which came in a 10" diameter.  If you open the box and see the lettering EMC along the optical tube then it's a classic.  They came in f/10 only.  Depending upon condition and functionality of the electronics, it could be worth $800 for a motivated buyer.  The 90's models were made in the US, had no plastic or foreign made parts and were assembled in Irvine, CA.  I still have my classic LX200 10" OTA in my stable and is a fantastic planet killer.

 

The "classic" LX200 10" was initially offered at F/6.3 as an option, although the vast majority are F/10.

That's a Meade 2120 Premier (the mount is basically their LX6). This was the last model before the LX200 was introduced. Likely the scope is from 1990 or 1991. It's an f/10 model.

 

I'm not sure of the value, but I used to have this exact same scope and it had terrific optics and was a fantastic scope. It is not GOTO, and depending on the options, the display on the hand controller may show the RA and Dec of where the scope is pointed (once it is aligned). It's tough to tell from the photo if there's anything behind the red clear plastic "screen".

 

Nice scope! :)

Oh! You can read up all about that model (and many others) in Uncle Rod's SCT guide...

He talks about the Premier (Premiere) series starting on page 38! :)

On the ota is "Meade Quarta" the pic was too large to upload but the important ones came through.

 

And before we get too excited, a peep into the ota at the mirror, spider webs and debris on the mirror's surface,,,,,,,,,,,,,,

 

Inside the controller, nothing behind the red screen, the three top buttons were basically blank fill the hole buttons. 

 

Thanks for the replies bbqediguana, and the rest, unless the mirror cleans up it's a giant paper weight, we'll see, 

 

Anyway gang, thanks for the help.waytogo.gif

Thanks for the link bbqediguana, good read.

 

From what I've found it's a 1992 LX6. 2120 f/10

Coolness. This is one of my favorite visual scopes...

 

LX6 (9-21-2015)-3j.jpg

 

The handbox was designed primarily to assist with manually guiding a camera and isn't particularly useful for visual. The scope doesn't need it to run, just plug it in, and the R.A. motor turns on.

 

Have fun!

Take notice to the "S" and the color that encircles it.  If I am not mistaken, yours is "just" the LX6 with the reddish-orange color encircling the "S".  The "premiere" version had a Meade insignia surrounded in green instead of the "S".  I owned on of each back in the day, and being that long ago, I "may" have the 2 mixed up. gramps.gif

Well, like I said earlier, I'm not to excited by it, the mirror has spider droppings on it, which from my experience in the past pretty much ruins the coatings, the mirror and corrector get dropped int he soak tank for cleaning tomorrow, about the only thing of value is the 50mm plossl, he has all the camera attachments, no diagonal, no camera, and there is going to be a lot of clean up which will keep me off the streets this weekend, couple of smaller Orion plossl's, one all white, never seen one like it, the two stock plossl's that came with it, a focuser for the visual back, couple of filters,,,,,,, a visual back Orion Ultra Block, the original straight through 8X50 finder.

 

A trip to the hardware store for some fasteners to secure the scope to the tripod,  

 

I understand the potential of it and all, it's just too heavy for me to use comfortably.

I'm figuring the tfov of the scope to be around 1.4°, am I close?

LX6s only came in in F/6.3. 

 

As far as the logo differences, I think the "S" in the red logo is the significant thing.  I think it stands for "Smartdrive"-- Meade's periodic error correction.   PEC was on the spiffier Premiere models, but not all Premieres.  And I think it only became an option after the launch of the Premiere line, but I could be wrong.

 

I'm figuring the tfov of the scope to be around 1.4°, am I close?

Well, the largest fieldstop you can get in a 2" eyepiece is about 46mm.   

 

57.3*46/2500 = 1.05 degrees

 

How did you come up with 1.4 degrees?

Skywatchr above said it's not a Premier scope because of the color surrounding the "S". However, I have a Premier and the color surrounding the "S" is red/pink, so that is not a given. The best way to know it to look at the worm gear. The Premier had a very fine tooth pitch to the worm gear compared to a standard worm.

jallbery above stated that LX6s only came in f/6.3. That is also a misunderstanding as they made both f/10 and f/6.3. I have had both. I also used to have a website named Telescope Bluebook where I listed the key elements, year of release, etc. of hundreds of telescopes.
