David,
I live a few minutes drive from the Losmandy shop. Scott was a member of my club the LAAS (Los Angeles Astronomical Society) back in the day when I first joined back in the '70's. Having been around the shop a bit, nosy and mechanically curious I've seen various versions of the new hybrid mounts which were in flux for a long time. When I first saw the hybrid that would become the GM811GT the RAEXK was not a part of the basic specs. But IMO this is a high spec level and I'm happy Scott has added so much value to these mounts while keeping the price approachable compared to his real competition in the upper end of the market.?
I resisted the urge to buy the RAEXK for a long time but I will be the first to admit that I was an idiot for doing so. The RAEXK even before the tucked motor update added significant usable movement to the RA and DEC axes. With the G11G spec tucked motors the G11G mount's EQ movement limitations are really only limited by the imaging train length or the focuser length from the rear of the saddle and the tripod legs, not the motor or mount itself any longer.?
