Hi Sonny,
I am also curious what you have your limits set to ?
I have the RAEXT and 12" Ext, ( but I removed my original 4" riser ? from the FHD tripod...)
(With my imaging train on a ED102 with a Celestron OAG and ZWO cameras I can only get my limits to 96 degrees before I get worried)
Thanks,
Astronut Tim
