this has been a terrific mount for me but i have gone equatorial. M10 threading. one arm has been drilled (by a machinist) to fit the gm8 saddle plate. he also made a washer which allows a broader base of support for flat top tripods. the counterweight shaft has some set screw marks on it. everything else looks very nice. motions are quite smooth although i believe all but the very lightest scopes benefit from a counterweight.
the tripod and mt 130 are not included.
$360 plus shipping. trade involving pronto ota considered.
