VIXEN ED100Sf with Vixen GPD2 Equatorial Mount With Star Book S

The Scope:  The ED 100Sf is now available for the first time in the US. It is the big brother of Vixen's best selling ED80Sf. This 4" APO refractor features high-grade glass and quality components.  The ED 100Sf is now available with Vixen's Dual Speed Focuser.  Vixen's apochromatic refractor has an extra-low dispersion (ED) lens which depresses residual aberration to ahcieve a high level of performance. Coupled with a medium f/9.0 focal ratio, the ED "S" series provides sharp, high contrast color-free images.  For the astronomer that wants the best value for the dollar in a 4” APO, this is the one to get.

The Mount:  Vixen has been making versions of the GP mount almost since the inception of the company.The original Polaris Mount, evolved through refinements to the Great Polaris Mount and now, with further refinements, is the GPD2 Mount. As with all versions, the GPD2 incorporates the Star Book S with complete GO TO system as well as same care and precision that is evident in all Vixen products. This includes 100% inspection and testing on the drive gears of all mounts.You can rest assured that when you purchase a GPD2 mount it is going to work right out of the box. To give you added assurance when this mount is purchased through an authorized Vixen Optics dealer, a 5 Year Warranty is included. 
The GPD2 equatorial mount is the stronger and heftier of the GP mounts. With its solid steel R. A. and Declination axes and brass worm gears, this mount will hold up to years of heavy use. In order to assure accurate tracking for astrophotography, the worm gears are especially machined to a very high precision that minimizes periodic error. The GPD2 Equatorial Mount is equipped with a polar axis scope with a built in variable intensity illuminator.
