GSO 8'' Classical Cassegrain Telescope

GSO 8'' 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 28.6% Allow Much Better Contrast Than Similar Schmidt Cassegrain

Features 

 99% Reflectivity Mirror 

These Mirror Are Specially Coated To Provide Maximum (96%) Light Reflectivity To Get The Best Contrast Available For Image Or Visual Usage. 

Precision Dual Speed Focuser

Most Standard SCT Comes With Standard Focuser, Our Classical Cassegrain Telescope Comes With High Quality Dual Speed Linear Bearing Focuser Allow Precision Focus And Sharp Image. Linear Bearing Prevent Focuser Flexure While Focusing And Locking

High Quality 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.
