Description of Orion 80mm f/11.4 Refractor Telescope Optical Tube Assembly
This quality 80mm refractor makes the perfect guide scope for doing long-exposure astrophotography. The 80mm-diameter air-spaced achromatic lens has a focal length of 910mm (f/11.4) and provides plenty of light collection for targeting faint guide stars. Multicoatings keep light loss from reflection to a minimum. The rack-and-pinion focuser (1.25") is made of aluminum and features a focus lock knob. The aluminum tube is finished in glass black enamel and has an aluminum dew/glare shield. Six internal baffles prevent internal glare and provide great image contrast. No finder scope, diagonal, eyepiece, or guide scope rings are included. We recommend purchase of #7831 Guide Scope Rings and #7382 Guide Scope Mounting Bar for attachment of guide scope to SkyView Pro or Atlas mounts.Telescope Accessories
