The Starfield GEAR90 f/6 Triplet APO Refractor will take your wide field imaging game to new levels. Using multi-coated FPL 53 (ED) glass, you'll experience sharp stars and amazing contrast.
The StarField GÉAR series comes with a retractable dew shield, an optical test report, heavy duty CNC rings, a Vixen style dovetail, a handle designed to mount optional accessories, and a hard case with die-cut foam.
A 2.5" Rack and Pinion dual speed focuser with ball bearings is standard on the Gear 90 mm f/6 Triplet. It comes with a Camera Angle Adjuster (CAA) with self-centering rotational lock (no set screws to come loose), supports the use of both 1.25" and 2" eyepieces and accessories, and has an M63x1 female thread on the eyepiece side.
The included camera angle rotator will be much appreciated as it will let you frame up your object easily without adding flex or changing your focuser position, and the focuser itself can be fitted with an optional focus motor if you'd desire a bit more control.
Weighing in at just 9 pounds, the Gear 90 mm can be easily be used on a mount with a payload capacity of 20 pounds; making your whole set up reasonably portable.
An 0.8x adjustable reducer is available separately for astro-imaging with APS-C sensors.Gear Series 90 mm f/6 Specifications...
