GSO 8'' F/4 Imaging Newtonian Telescope

8'' F/4 Imaging Newtonian Telescope

Imaging Newtonian Are Economical High Performance Telescope Specifically For Astrophotography. F/4 Focal Ratio Allowing Rapid Capturing Of Dim Deep Space Objects

Imaging Newtonian Provide Good Wide Field Image For Deep Space. These High Performance Newtonian Are Portable And Light Weight, But Designed Using Quality Material And Finishing. Lightweight Telescope Allow Better Mount Tolerance (Less Strain To Mount) Enhance Stability And Image Quality. This Includes Solid 2'' Dual Speed Focuser Providing Accurate And Stable Focus Point For Astrophotography.

Coupled With Our Optional Coma Reducer, This Will Give You Ultra Wide Flat Field Image For Deep Space Imaging

Features 

 94% Reflectivity Enhanced Aluminium

These Newtonian Mirror Are Specially Enhanced Coated To Provide 94% Light Reflectivity To Get Better Contrast Available For Image Or Visual Usage. High Quality Precision Parabolic Mirror Offer Best Image Quality

Precision Dual Speed 1:10 MicroFocuser
