GSO 6'' Classical Cassegrain Telescope (Used)

GSO 6'' F/12 Classical Cassegrain

Classical Cassegrain Telescope Are Excellent Choice For Both Visual And Long Focal Length Imaging Class Telescope. Classical Cassegrain Features Flatter Field Of View With Very Minimum Coma - Significantly Better Than SCT, Can Compete With EdgeHD/ACF Optics

Open Optical Tube System Prevent Dew Formation Thus Eliminate The Requirement Of Dew Shield. Comes Includes With Dual Speed 2'' Focuser. Fixed Primary Mirror And Secondary Preventing Mirror Or Focuser Flop And Image Shift Issue In Maksutov Or Schmidt Cassegrain.

Features 

 96% Reflectivity Aluminium

These Mirror Are Specially Coated To Provide Maximum (96%) Light Reflectivity To Get The Best Contrast Available For Image Or Visual Usage. Compund Telescope Are Very Compact Due To The Optical Design

Precision Dual Speed Focuser

Most Standard SCT Comes With Standard Focuser, Our Telescope Comes With High Quality Dual Speed Microfocuser To Allow Precision Focus And Sharp Image. Our Telescope Comes Standard With 2'' Precision Focuser

Internal Baffle

Classical Cassegrain Telescope Are Built With Baffled Tube To Provide Maximum Contrast And Prevent Stray Light From Disturbing Viewing Or Imaging. These Baffle Systems Only Found In Higher Quality Telescopes

Wide Flat Field Image

Classical Cassegrain Optical Design Provides Relatively Flat Field With Very Minimum Coma. These Provide Excellent Round Stars
