Description
GSO coma corrector for Newtonian telescopes from f/4 and slower
... an effective Newtonian corrector with better field illumination by M48 connection instead of T2

GSO Newtonian coma corrector

This GSO coma corrector can be placed completely inside a 2" focuser and offers a high grade of correction and also a low degree of vignetting. The generous back focus of 70mm allows the use of off-axis-guiders.

Good field correction, also with f/4 Newtonians:
In opposite to easier correctors offering good performance only from f/5, the GSO coma corrector works also with f/4 systems.

M48 thread connection for good field illumination:
Especially fast Newtonian systems suffer vignetting when a T2 corrector is used. The short TSOAG9 off-axis-guider can be connected directly and no back focus is wasted by adapters.

The GSO coma corrector characteristics:
-- Suitable for Newtonian telescopes from f/4 and slower
-- M48x0,75 - 2" Filter threads
-- Offers 44mm of illuminated field diameter - even full format sensors can be used.
-- Long working distance (70mm) - enough space for off-axis-guiders and filters.
-- No changing of the focal lengh of the telescope

Connection:
-- Telescope side: 2" barrel with 2" female filter thread
-- Camera side: M48x0.75 male thread - fits directly to further adaptions, filter drawers, off-axis-guiders and more.
