This is a substantially engineered mount manufactured by Larry Myers in the USA and purchased new 13 years ago. The MI-250 comes with a Gemini Mark II controller, as used on Losmandy mounts, and is configured for use at UK latitudes.

Also included are a portable pier, which could easily be adapted as an observatory pier, a polar alignment scope and counterweights.

The mount has an instrument load capacity of 75lb (34kg) due to its substantial nature and the the strong focus that Larry put on engineering things “right”. For transportation, the DEC assembly can be detached from the RA assembly, making the MI-250 straight forward move and erect by a single person.

Mountain Instruments has now closed down but there is an active user group here: and information from Larry’s original web site is here:

This mount is engineered with longevity in mind and here is a link to an MI-250 in use at an Australian observatory:
