any recommendations for current or old ten inch gem newts?

 

and why do the most common GEM newt for sale seems to be 10 inch starfinders?

 

consider the RGs and caves already mentioned (though astro-eye-candy is always welcome!)

I suspect that the Meade "Starfinder" series of equatorially-mounted Newtonians were quite popular, back in the day, hence their being more commonplace on the used market.

 

Had you asked about twenty years ago, I would've suggested this Parks instead...

Both Parks Optical and Scope City are defunct, however that Scope City website is still available for historical reference, hence no orders may be placed.

 

There is Orion's 10" f/4.7 Newtonian OTA...

An EQ5-class or EQ6-class equatorial mount may then be selected to complement it.

The newer companies generally under mount their scopes for the same reason the Dobsonians started replacing GEM mounted ones. Because they answered some of the criticisms of the earlier heavy mounted Newts. It was pretty much the weight that killed them. If all you want to do is look thru the telescope, then all that bulky and heavy mount just made it harder to use. I have a couple of the older era mounts, a Meade DS-16 heavily modified with Byers gears and electronics and a fully restored Schaefer AT-9 that has the payload of an AP1100 and then some at less than 1/4 the cost. But all you get is tracking drives. But I am from that era so I don't need goto. I could convert it but what for? I don't have a 17" telescope I need to carry. I have a pair of 20 year old A-P mounts to carry almost every scope I have with push-to wirelessly with SkySafari and my Nexus II. More than I need.

I just bought a 10" Meade RG i am redoing. OTA is fine but someone painted the mount white.

I don't know why, but I hate white mounts.

 

it just seems, wrong. Sacrilegious even.

It's being ripped and stripped and going back to factory specs as i type this.

Without a set of good (i.e., properly usable) rotating rings, a Newt on a GEM is at best a pain in the neck to use. Literally... not to mention in the back, the shoulders, legs...  I started with a small Newt on a GEM 34 years ago and didn't know any better. Years later, I tried putting my 8" f/6 Dob OTA on a GEM. It reminded me not to do that.

 

I can understand the utility / necessity of it for imaging, but for visual? For me, no way. YMMV.  smile.gif

 

But FWIW, I do like white scopes and even white mounts.  Maybe A-P is to blame... LOL

The use of Wilcox-rings has been successful for some...

Fine, rotating rings cost $$$.  

 

In any event, when using a Newtonian on an equatorial, it works best if you're not flitting from one object to another in the span of fifteen minutes.  Rather, it is for observing only a small handful of objects, and over a span of a few hours; for spending quality-time with this sprite and that.

I bought mine in 1986 and I still use it. Very good optically and the mount is a beast. At the time you could order it in f/5 or f/6. Mine is marked on the back of the mirror as f/4.9. I’ve been very happy with it.

Parks didn't offer the 8" as an f/5, only an f/6.  The 8" f/6 OTA was $899, but I called Parks and asked for an 8" f/5, and they obliged, for $200 more.

 

And yes, the Parks mirrors are out of this world.

I knew that about white mounts, but I prefer the black ones nonetheless; incognito.

they also harm night vision. if he's at a dark enough spot for it to be an issue, I'm jealous.

can you even get fully functional 10 inch starfinder GEMs anymore?

There is a fix for that, a neat new invention called paint.

I have the best paint stripper.  Already got the pier and legs and some parts painted.
