NEW William Optics Digital Display Gauge (DDG) focuser for serious astronomers and astrophotographers!!

We are proud to present this innovative device from William Optics, the first ever seen on an astronomical telescope. This prominent, revolutionary design is primarily geared towards serious amateur and professional astrophotographers. The Digital Display Gauge - DDG - allows you to take precise focusing readings down to two decimals instantly. With this new device integrated into your telescope you will no longer need your old red flashlight during observations or imaging of the night sky!

This premium (2") 360 degree rotatable DDG focuser comes with two locking screws on angled positions for heavy load applications, a silk-smooth 2-speed microfocuser, a 2" to 1.25" adapter and a thermometer installed into focuser knob!

This focuser has a 96.9mm (3.81") diameter base plate that is designed to fit Synta-made (Skywatcher, Celestron, Orion and more) refractors. It will add functionality and style to your observations. It will assure imaging without any image-shift, better star testing, and a touch of William Optics's quality. The ideal upgrade for your refractor of any size!

Fine Focusing
• 2" DDG focuser: smooth and precise. Zero image shift. 360 degree rotatable.
• Now with a new one-piece dual speed reduction.
• Solid as a rock, smooth like a feather.
• Brass compression rings on both the 2" drawtube nosepiece and 1.25" eyepiece adapter.
• Large aluminum knobs.

Impeccable Fit and Finish
• Large drawtube locking thumbscrew with adjustable tension.
• Two locking screws on angled positions for heavy load applications. Your new focuser will accommodate any accessory such as CCD cameras, large eyepieces, binoviewers, etc.
• Installed thermometer.
• Long drawtube (80 mm).

Easy to Mount
• Requires only minimum assembly on your part. Replacing your bundled die-cast rack-and-pinion focuser has never been easier: release 3 screws, and get ready for observing in 3 minutes!
