The iEQ45 with William Optics GTF102

We've partnered with William Optics to give you the best of both worlds!

The Mount

The iEQ45TM mount offers the next generation GoTo technology from iOptron —not to mention built-in 32-bit GPS. With a payload of 45 lbs. balanced – it comes standard with a calibrated dark field illumination polar scope and a sturdy 2-inch stainless steel tripod. It also fits both Vixen and Losmandy-type mounting plates. Its lighter weight (only 25 lbs.) makes it much easier to carry.

The Optics

The stunning new 2013 William Optics GTF 102 five-element super APO is the new jewel of the apochromatic refractor world. Superb quality for imaging and visual at an affordable price!

From the pristine white finish on the CNC to the elegant red beauty which has more than just good looks... New GTF 102 features total 5-element in 2 groups design by using high-quality FPL-53 extra-low dispersion glass that reduces any secondary spectrum to an unbelievable degree, the second group of ED element (flat field corrector) is correcting the edge of flatness to the best quality (cover up to 40mm of image circle).
