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. This instruction m

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

Bushnell Night Vision products amplify existing light, allowing you to see in dark conditions too dark for the naked eye. HOW NIGHT VISION WORKS Bushnell Night Vision products collect and amplify existing light through the objective lens, which is then focused on the image intensifier. Inside the intensi

Seeing conditions often preclude the use of the 5.2, so I sometimes substitute the 7. It can be used a bit more often, but doesn’t provide quite the detail of the 5.2 when seeing is really good. The view through the 40mm is spectacular on extended objects. Its 2° field is almost half that of many finder scopes, making a finder scope unneccessary.
