A 07/11 2 Congratulations on your purchase of an Orion f/3.9 Newtonian Astrograph! These powerful imaging telescopes feature “fast,” high-quality parabolic optics, a 2" dual-speed Crayford focuser, and excellent mechanical construction with some special features. Optimized for astrophotography with DSLR and astronomical CCD imaging cameras, our f/3.9 Newtonian Astrographs are capable of delivering breathtaking imaging performance – for beginning to advanced astrophotographers.

Collimating the Optics (Aligning the Mirrors) Collimating is the process of adjusting the mirrors so they are aligned with one another. Precise collimation of the optics is especially critical for fast Newtonian optics such as in the f/3.9 astrographs. If the mirrors are even slightly misaligned, image quality will suffer. So you should check the collimation before every observing or imaging session, to make sure it is dead- on. The process of collimation is a relatively easy and can be done in

A 01/08 Congratulations on your purchase of an Orion® EON™ ED Apochromatic Refractor optical tube assembly. The exceptional optical and mechanical quality of your EON refractor will provide you with a pleasing telescope experience. The ED glass in the objective lens yields extremely sharp, high-contrast images with virtually no color distortion compared to a standard refractor. The smooth and fine movement of the dual-speed Crayford focuser allows for easy and precise focusing. These instruction

This focuser is intended for use with the Orion ED-80, ED-100, Astroview 100, 120ST and the SkyView Pro 120mm. If you do not have one of these refractors, the focuser may not be appropriate for your telescope. Crayford focusers generally perform better than rack-and pinion models because the design eliminates “focus shift”. Focus shift is when an image moves position in the eyepiece when it is being focused. This is very hard to eliminate in rack-andpinon focusers due to slight gear and toleranc
