I thought I would post some pictures of a Pentax MS-3n equatorial mount that I recently aquired. This mount is sold in Japan with the Pentax 75mm SDHF refractor. Stated accuracy is +/- 10" and carrying capacity is listed as 6 kilos (13.2lb). The weight is about 25lb including counterweight and clamshell ring. This is definitely the most well built small equatorial mount I've encountered.
