Slik, the company known mostly to photographers (like me) for tripods, has produced a line of items for astro photography - https://slikusa.com/...tro-photography. I doubt I would invest in the tracker itself, but what I find interesting is the Micro Adjustment Mount. It looks solid (and Slik typically makes solid things), and it's less expensive than the Williams Optics wedge. Maybe I will investigate it as a replacement for the wedge that comes with the Skyguider Pro.
Thought y'all would like to see it, since I didn't see it referenced on any posts here when I ran a quick search.
