Newtonian Astrograph

AG Optical Systems has discontinued our premium Newtonian Astrograph line to concentrate on our iHW and iDK products.  We have a limited number of Wynne corrector optics left so we are building a limited run of our high-performance Newtonian astrographs.  Please see the features and pricing details listed below.  We encourage you to compare our product and pricing to our competition!!!

 

AGO Newtonian astrographs are a photo junkie's idea of Nirvana.  By combining large aperture, fast focal ratio, corrected optics in a lightweight, stiff, and thermally stable carbon fiber tube AGO has created an instrument with a singular purpose:  to devour photons and precisely focus them on your CCD camera's chip.

AG Optical Systems Newtonian astrograph offer the best value and performance in the high-end Newtonian astrograph market.  On a feature by feature comparison, there is no comparison:  AG Optical Systems is light years ahead!
