DESCRIPTION

William Optics ZenithStar 103 f/6.9 Doublet Refracting OTA Telescope

The ZenithStar 103 (4.06-inch) aperture f/6.9 imaging APO is made in three colors: Gold, Blue, and Red. It has an innovative Bahtinov Mask Cover (Patented) included!

This beautiful scope has everything you could want from a refractor such as extreme sharpness for clear details and APO color correction. It has all the benefits of the ZenithStar family at a price that is hard to beat.

The William Optics ZenithStar 103 features an f/6.9 FPL53 Doublet air-spaced APO in a CNC machined ultra-high precision lens cell. With an x0.8 flattener, this can also become an f/5.5.

Comes with 2.5-inch rack-and-pinion ultra-robust focuser with 1:10 dual speed

Thanks to its design, there is NO image shifting, making this a real treat to use in astrophotography!

Despite its 103 mm objective, the scope is still very compact and solid. Many airlines will accept it as carry-on luggage! Perfect size for serious observations of deep sky objects and planets. Solar observations are possible with proper additional equipment.
