Note on price: Due to the weight and sizes of the various shipping boxes, these mounts are expensive to ship from California. Please allow an additional $220.00 USD (plus applicable tax) on top of the price listed above. We will add this charge to your order when we process your payment.
Note on power supply: If you are powering from the AC mains, we recommend Losmandy's 15 volt power supply. This will ensure reliably sufficient current that a 12 volt supply may not quite provide.
The upgrade from the G-11 to the new G11GT accommodates a heavier payload of 34kg (75 pounds.) The mount features a detachable declination axis and more streamlined motor mountings.
