One of the reasons why I wish I lived in Australia is the manual Saxon EQ-5, and in black. I prefer black mounts, and the only ones I have in black are an EQ-1 and an EQ-2; none larger. Both of my alt-azimuth mounts, small and large, are white.

Orion Telescopes, of California, proffers a black EQ5-class mount, the "SkyView Pro". But its design is seemingly proprietary, unlike the rest of Synta's manual EQ-5s. Still, I knew that the Orion was the same, on the inside at least. I was just on the verge of getting the Orion when this listing on eBay appeared...

I got my own out of that lot of four, and as far as I know, there will be no more, ever. It was a deal of a lifetime. Although, I hesitated, after having first seen the listing, as it did not come with a tripod. A day or two went by, and then it dawned on me: the tripod of the Celestron CG-4, and that of the discontinued Meade LX70, are identical, both with 1.75"-diameter tubular-steel legs, the uppermost portion.

I don't mind crawling upon the ground, then looking upward. Then, I didn't shorten the leg's extensions, of course not.

I had gotten the 16" pier for the CG-4...

...and to a tolerance of approximately 1/64". I also painted it, "safety blue".

In order to eliminate the tripod's spreader/tray, where the legs join the tripod-hub, I had replaced the twelve(!) "leatherette" washers, four for each union...
