GSO 20'' Carbon Fiber Truss Tube Telescope

20'' F/8 Thrust Tube Ritchey Chretien Telescope

Ritchey Chretien (RC) Telescope Are Leading Astrophotography Class Telescope. RC Are The Main Telescope In Most Of The Large Observatory And Even Hubble Space Telescope

RC Telescope Provides An Exceptionally Flat Field And Coma Free Image - Allowing Pin Point Stars All Across The Image. Most Newtonian And Cassegrain Suffers From Coma Where Image Is Sharp At Center And Become Bloated At Corner. RC Telescope Eliminates This Completely

RC Telescope Design Was Previously Not Affordable By Amature Astronomer. With New Manufacturing Technique, Previous Scope Costing Hundreds Of Thousands Now In Reach Of Budget Astronomer. Quality Are No Compromised. These RC Features A Solid Tube Construction, 3'' Dual Speed Focuser And A Multi-Layered Internal Baffle. These RC Provide Excellent Imaging Platform And Also Good Enough For Visual. Available In Size 6'' To 20'' RC (15cm-51cm)

Features 

 99% Reflectivity Dieletric Coated Aluminium

These Mirror Are Specially Coated To Provide Maximum (99%) 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 1:10 MicroFocuser

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 3'' Precision Focuser
