GSO 6'' Classical Cassegrain Telescope

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 Flop Issue In Schmidt Cassegrain. Smaller Central Obstruction Of Just 33% Allow Much Better Contrast Than Similar Schmidt Cassegrain

Features 

 94% Reflectivity Coated Aluminium

These Mirror Are Specially Coated To Provide Maximum (94%) Light Reflectivity To Get The Best Contrast Available For Image Or Visual Usage. Compund RC Telescope Are Very Compact Due To The Optical Design

Precision Dual Speed Focuser

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

High Quality Internal Baffle

Our Classical Cassegrain Telescope Are Built With highest Standard 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 Up To 38mm Diagonal At All Corner Of Image. Most Advance Observatory, Includes Palomar, Hubble Space Telescope And Very Large Telescopes Uses Ritchey Chretien Optical Design
