LXD75 Value
« on: December 24, 2017, 01:52:58 AM »
I am in the process acquiring parts to compile a scope and also have encounter Meade LXD75 mount.  The owner is requesting $450 which as far as I can gather is a lot.  He reports the mount was seldom used and is in good shape.  My strategy would be to mate the mount into an 8" SCT which has yet to be acquired.With that said, what's fair price to offer you?

Thank you

$450 seems pretty reasonable to me if it's in good shape.

Personally I would hold on for a cheaper one but if you think that fits your needs and that you might not find another one soon you might have to go for it. Make sure that the goto works well and no oddball noises. Check the feel of the backlash, too.

When new, they were ~$599-$699
The earlier version had 1.75" legs, while the later version had 2" legs
The later version is the one to get.
The casting for the mount head had problems, and often the threaded hole for the center shaft was slightly conical in shape, allowing a VERY easy cross-thread on the center shaft,
which ruined the mount unless the hole was drilled and a helicoil installed.
Motors were unreliable, and mounts were often returned with at least one motor non-functional.
When they worked, they worked fine for scopes up to an 8" SCT or a 6" f/6 newtonian.
Anything heavier was an issue, however.
When they didn't work (which was very common--maybe 33% in our shop), they weren't much good as a mount because they were not usable manually, only with the GoTo controller.
I would peg a good price for a fully-functioning one at about $300.

I'm with Starman on this one. I had one and it gave me nothing but trouble. And if you can't use it manually when you choose to, why bother? $300 is fair but I wouldn't get it at any price. Sorry to say that. Also, an 8" SCT was right at the limit of that thing. Not what you really want in a mount. Have you considered anything else? An Orion, perhaps? There are others here who would be happy to recommend a more suitable mount. Stay tuned for them...

I have an early model LXD75 and it has 2" legs. It worked fine with great go-to's for 10 years until the RA board gave up. I guess I had a good one.

I bought one in 2004. I was a Meade dealer at the time and I seem to recall I had to do some trickery with ordering SKUs to get the 2" tripod legs. Out of the box, it was a mess. Like, can't even use it mess. However, at the time, we had a HUGE dead-on-arrival problem with both Meade and Celestron. As in, so bad we stopped selling any scopes in the factory boxes because we found we had to inspect every single scope to make sure they actually had optics in the tubes!

Anyway, the show-stopper problem it arrived with was that the coiled cord between the handpaddle and the mount was flakey and would result in the controller and mount getting out of touch with each other. I made a new one out of ethernet cable and that solved all the show-stopper problems. However, GOTOs were very inaccurate. I then tore the whole mount down, removed all the adhesive from inside it (I'm sure someone mistakenly called this crap "grease"), finished the machining process, and removed the spare washer. Yes, a spare washer was stuck inside of it between the RA main casting and the ring gear. Stuck as in jammed to the point I had to get the parts separated with a hammer and punch. Spare washer as in "didn't even fit any part of this assembly, clearly from an entirely different machine" washer.

So, once I did that, it actually has worked well ever since. I used it for a number of years, then stored it for a long time. When I took it out of storage, it turned out I had chosen poorly when I re-greased it and I had to put new bearings into it. The only thing that still bothers me a little is, as noted above, the really dodgy connection between the mount and the tripod. I was actually looking at that last night, thinking about having a piece custom machined to make that more solid.My advice on the LXD75 would be this: It's a perfectly fine, easily usable mount once you finish building it since Meade clearly couldn't be bothered. It's easy enough to resolve the problems Meade left inside by yourself, so if you can get one at a decent price, go for it.

LXD75 mounts are also notorious for burning out motor controllers if they are not well balanced. One recommendation I received is to put an approprate current light bulb in series with the power supply. Excess current draw will cause the filament in the bulb to light, dropping power to the mount. Reinitializing the mount is a lot easier than rebuilding a blown circuit board.

I had the earlier model with the less robust tripod. I used an 8" Schmidt Newt and 4" Apo on it. It worked 8.5 years until I sold it with the SN8 for $500. It still worked at the time. I did have to tinker with the gears a couple of times. Just because it has 9 speeds doesn't mean you should use the 9th (highest) speed. Tried that once, gears went flying in all directions. Ok not really that bad, but I never did it again. Basically I view these as 10 year useful life mounts, assuming regular use. It is probably older than 10 years so it really depends on if it really has been rarely used. If it is in good working order, I would think $300 would be a fair price. If it has only been used a few times and is basically in mint condition, maybe $350-400. Keep in mind a used CG5 (which I got next and consider somewhat superior) typically goes for $400-450.

If you split the $500 price for my old model evenly between the SN8 and the LXD mount, then I got about $250 for my mount (the earlier version with stamped aluminum tripod). So $300 seems like a fine price if it works well. Will it be a forever mount? No, but if you are looking at used Chinese mounts, you probably can't afford a forever mount.

Thanks for all the replies. After reviewing some photos the owner sent me and a disclosure about some handset issues I decided it wasn't worth the drive to further examine it. ATM I'm leaning towards just picking up a new exos-2gt. Also, you're correct I am dipping my toe back into astronomy and am not looking to dump a bunch money into this until I'm sure which direction I want to go in.

The one odd thing about the Exos is it doesn't have a Tracking mode. Only full goto or full manual. Which is fine for a lot of folks.

lol, the Exos is pretty much an LXD75. Speaking of the LXD75 mine has been tuned and is awesome, though I think the SN10 I have with it might be a tad bit heavy.

I own two LXD75s; one from early production with the 1.75" legs, one from late production with 2" legs. They were my workhorse imaging mounts for many years before I replaced them with a pair of Atlas mounts. The LXD75 was an excellent value, though they weren't perfect. The most common problem seemed to be lose set screws, easily fixed with a spot of Loctite. They also benefited from a bit of tuning to snug up the gears and to reduce backlash, again, easy to do. My LXD75s continue to serve me well as visual mounts, and occasionally for unguided wide field imaging. Valuewise, $450 is probably a bit high, $300-$350 seems to be the going rate for examples in good condition.

My LXD75 (w 2" legs) serves me well since I bought it brand new in, I think, 2007. So, 10 yrs. Never broke down. It carried a 6" f/8 achromat for 6 yrs, now carries a 6" f6.5 achromat (for a yr so far), and from time to time a 4" f/9.8 achromat (for some 4-5 yrs). Not bad from a more-or-less an introductory rather cheap mount/tripod.

Reminds me of this Longfellow rhyme:
There was a little girl,
 Who had a little curl,
Right in the middle of her forehead.
 When she was good,
 She was very good indeed,
But when she was bad she was horrid.

Apropos? Seems so.
