I have been toying with the idea of de-forking my LX-50 10 " and wondering which goto mount would be able to handle it. Cost is a factor so I would consider an older model of whatever will work.

Thanks for any input and Happy Thanksgiving to all!

Rod

That is what I did Rod. I had the LX6 2120 10" and found a used LX200 mount for it ,extremely reasonably priced and it works great.
Now I am in the process of replacing all the caps for protection.

Did you have to make any modifications to the LX-200 mount, or did the scope just fit right in?

I had no problems with changing it over.All the screws mounted in the same holes from the mount to the scope.By the way it was a Classic to Classic refit.

I'd avoid the LX200 and look for an LX200GPS. Parts are getting scare for the LX200 and possible repairs are getting pretty steep. OTOH the 2120 weighs about 30# with a proper dovetail. Add another 5# for good measure, so we're looking at a mount that will handle at least a 40# payload.

In the cheap area ($650-700) you're pretty much limited to the non-goto Orion Atlas (Synta HEQ-6) For about a grand there's the goto Atlas or Celestron CGEM. At $1500 there's the CGEM-DX, Losmandy G11 (not Gemini) and the iOptron Q45. The $800 Meade LX80 would have been a good choice it it wasn't such a disaster. There's talk of a LX85 coming, but I wouldn't want to be an early adopter. I have a LX80 I picked up for $100 with bad electronics that I'm playing with to give you an idea of the value of that investment.

I've got a push to Orion Atlas, a Losmandy G11 and probably enough parts to convert your LX50 mount to Autostar goto for sale. PM me if interested.

Hi Rod

For what its worth I de-forked my lx50 10in and mounted it on a CGEM.

Works like a charm now. This mount is up to the challenge if you decide to go that route. :winky:

I deforked my LX50 and put it into LX200GPS forks in 2007. It works fine for me..

Yep that is the way I am going to go. I am working with someone and I am getting a LX-200 setup from them.

I am sure it will work out great. The biggest problem is that here in Mn. it is downright COLD out there!!

I think you may find that one of the main reasons most people de-forked their LX-50 (and some LX-200's) is because the component weight of the scope and forks is quite a bit and not a great ergonometric design for taking on and taking off a tripod. Putting it on a GEM, for instance, changes a 50-60 lb. package to lift onto a tripod into two ~30 lb. components instead. That, plus getting a good and reliable go-to system were the two big reasons for me to de-fork. Secondary to that were the accuracy of the worm gears and the ability mount other scopes and accessories in a more flexible manner (i.e., with a side-by-side plate).

The biggest trade-off in going from a fork to GEM is, of course, that you end up needing to do a meridian flip at some point in the night with a GEM. This wasn't a big deal to me, but it might be to another person.

In any case, this is actually one of the easier things you can do with the LX-50... I am glad I did and never looked back.
