Mountain Instruments MI250 Mount

[cventer]

Selling my Mountain Instruments Mi-250 goto mount. This mount is in excellent condition and always housed in an observatory.

I measured Peak to Peak PE of +-3 arc sec for this mount using pempo (that is without PEC enabled).

Comes with Gemini Goto System with Level 4 eproms.

Has twice the imaging payload of a G-11 for only a little more money.

That's a great mount and a bargain Chris, that would go very nicely with an AG10, 12 or 16 actually....

Are you selling the pedestal too..? I have fond memories of that, modeled my pedestal on it even!

Hi Mike

Im holding onto the Portable pier for now.

This would easily take an AG12 or AG16.

I am pricing it to sell so fingers crossed someone needs a precision AP900 equivalent mount for near G-11 money.

[multiweb]

You wouldn't swap it for a G11 hey? ;) :P Bargain indeed. I would keep it if I were you.

Marc

I already have a G-11 as my field mount

Which is why I am finaly selling this. As I now have the Paramount Mx.
It is a arelative bargain but I guess still expensive so we will see. I dont need to sell it so wont be giving it away.

[Poita]

Do you have a suitable pier for it for sale, or be able to recommend one?
Their site says the mount is no longer supported, do you know if spares are still available?

[cventer]

While its not officialy supported, Larry Myers is still making the very large Mountain Instruments and will help anyone who needs it.

Having said that all the electronics and motors and gearboxes are from Losmandy. They Use the G-11 Gemini system so you can allways get spares.

The rest of it is built like a tank and is unlikely to need any support.

As far as piers go Im not 100% sure. My pier is not for sale, but any pier with 8" diameter or more should do. Quite a few threads here about Piers.

[Poita]

So the computer control options are the same as for the G11 then?

[cventer]

Identical.

its just a Gemini with gemini control panel nd hand paddle and motors etc....if you know how to use a G-11 Gemini then you know how to use this mount.

Hi Marc,

So this means I could fit Maxxon motors and Gemini to the mount? Let me know.

Cheers,

Steve

[cventer]

Steve

Not sure if you mean me ?

Yes you can fit Maxxon motors. In fact last model they made shipped with them. The mount already has Gemini system attached included in the price. But it does not need Maxxon motors. This things has 7.5 inch RA and DEC gear and precision matched worm. PE with standard Losmandy motors is excellent.

[cventer]

Just a quick update. I will also consider a trade of this mount for an stl1100 camera with cfw

[cventer]

Someone needs to use this mount.

Price is now $4800

[russellm]

When was the mount manufactured?

[cventer]

Sale Pending Payment and pickup

Hi All,

The dream mount is back on the market after the fastest "backout in history" I was planning to zip down from Wollongong on the weekend but plans all fell through.

Apologies again to cventer.
Pieter

[Davler]

pity about not finding out earlier I could have saved myself a few bucks I Just folked out 10 grand on an ASA ddm60. and I live in melb
How much did you pay for the paramount cventer? I was looking at the ddm85 at first there is a model that carries up to 100kg in that config a bit pricy tho

[cventer]

Mount back on market. Sale did not happen

[cventer]

PM me happy to discuss price I paid for Paramount

[cventer]

I have decided my unreasonable emotional attachment to this mount must be severed. Pointless sitting in my shed


$4200 :eyepop::eyepop::eyepop::eyepop:

Cheaper than a g-11 now folks with nearly twice capacity and accuracy.

[cventer]

added photo of payload capacity

[strongmanmike]

Can't believe this hasn't sold yet Chris :shrug: guys, this is an excellent mount at a very low price :eyepop: if I needed a good mount for under $10K this would be it
Mike

[cventer]

Agreed. I have someone coming tonight to buy it and a backup buyer now as well if this falls though so at least someone is going to enjoy it.

[Poita]

Oh I *want* this mount, there are just a string of items that have to sell before I'd have enough money.
I just hope something like this comes up again when the funds are in my pocket!

[cventer]

Sad and Happy to say this Mount is now SOLD.
