It seems like everyone wants the latest and greatest, cutting edge mount, many of which have teething problems or cost a fortune or weigh a ton or something else is an issue. Is there a good, reliable classical EQ mount for mainly visual use, time proven, spare parts abound, or is this just as rare as a unicorn?

I second orlyandico comments.The non goto versions of the losmandy g8s and g11 are solid,reliable performers.Replacement parts are readily available.The g11 that carries my c11 is sweet!Several years earlier I had a g8,again sweet.Just power it up and track.

Good, classic, reliable?

The Vixen GP/GPDX springs to mind.

I agree with the mention of the GP/GPDX. Parts should be available since it is still currently sold.

I think you can find an used Atlas for well under $900. They are a nice step up from the CG-5 and can be used for imaging also.

How much of a pain would an older G11 be for imaging at or less than 1200mm fl? I have an EQ6 pro that kind of works, but has a PE curve about a mile wide (20 seconds max unguided with a 200mm lens).

Roger,

I'm pretty sure an old G11 can manage much better than 20 seconds unguided with a 200mm lens!!

But a much cheaper option, although not as appealing, is to simply buy an Aeroquest worm for the Atlas/EQ6. It's only a little over a hundred bucks. You will get a worm that is at least 15" p-p and probably better. That's about what you'd get with an old G11. My Aeroquest worm (on my CGEM) is about 16" p-p.

However.. if your PE is that big (sounds like hundreds of arc-seconds), it might not be in the worm, but could be some non-concentric bearings or something. Ed Thomas would be in a better position to know if this is possible or not.

I bought it brand new, and it's been like this from day one. I suppose I could have returned it, but I didn't really care for the hassle. As big as the PE is, it seems to be quite smooth, as it autoguides out quite well, up to 1000-ish mm...

How about Cave with the 1.5 inch shafts? Further up the chain would be G11, and don't forget about the Push To Astro Physics. I put hundreds of hours annually on my circa 1994 AP1200DA. Can still get service with a phone call, replacement parts in a week or so.

For grab-n-go, the Vixen SP and GP

Yes, many parts for the Vixen GP can be obtained from one of the U.S. Vixen distributors. When Orion was a dealer they kept a lot of spares. I got a large flat rate box of 'em off eBazy. Need any motor covers :question: One thing I'm hanging onto are those spreader hinge pins!

I would not buy a used Orion mount due to the fact that if you ever need parts, they will not sell them to you.

Well, that's true to some extent. Orion doesn't make a single mount...and parts for the mounts they sell are generally available from other sources.

I don't know about spare parts (as the thing has never broken), but my Byers 812 is probably the best "push-to" mount around. Solid, transportable (but it ain't light) and reliable. Uses 120VAC synchronus motors so you'll need a frequency chopper drive corrector (an old Accutrak still show up on A-mart now and then). A good one costs about $2K or so.

OP never stated payload.... I guess everyone here are better mindreaders than I.

As an owner, I have had experience with the following for visual work:
- Byers or Schaeffer for heavy payloads > 40lbs
- Losmandy G8/G11 for middle-weight payloads 14-35 lbs
- Vixen Polaris for light stuff < 12 lbs.
