About
this Object This image is a first light image using the Keller .73 Corrector/reducer with my 10" f5 Astrograph. The addition of the Keller corrector required some modifications to the focuser placement in order to reach focus. The resulting pixel scale is 1.4"/px which us twice my typical seeing. This corrector/reducer offers excellent correction out to a diameter of 20mm, more than enough to cover my SXV-H9 Chip. I did not experiance any of the ghosting issue others have seen with the larger 3" corrector.
