My son wants to use his ETX-125 polar mounted for some photography. The Standard 884 tripod can be set for altitude but to adjust the azimuth requires rotating the whole tri-pod anawkward and inaccurate process. I told him I would make him a wedge with micrometer adjusments.

I had an unused tripod with cheap equatorial head on it and decided to remove the head (just required to undo the attaching bolt) and use this as the base.

A day and a half in the garage, a raid on the scrap steel and aluminium box, and I came up with this. Works perfectly.
