6 Inch Primary Parabolic Telescope Mirror Mounted for use as a Collimator This mirror was originally used in a holography optics lab as a collimator. It is mounted on a 6" x 8" 3/16" black (painted) aluminum plate but can be easily removed to be used as a telescope mirror, simply by unscrewing 4 clip mounts. It is an f/8 mirror (focal length 48.1 inches). If used in an optics setup, the aluminum plate has two tapped holes with 1/4-20 threads that are 3 3/4" apart that can be used to secure it to an optical table mount. Note that this is not a new mirror, however it is in reasonable condition except for a couple of edge fingerprints and a few other tiny spots. The fingerprints do not extend more than 3/8 " in from the edge and should be easy to clean. It is hard to tell if several of the tiny spots on the mirror are easy to clean or not. I haven't attempted it. The mirror should be fine for a backup telescope, or for an inexpensive do-it-yourself project where you do not need a perfect new mirror. If you are not satisfied, money cheerfully refunded if you notify me within 7 days of receipt, minus the shipping cost. I can ship either Parcel Post or Priority Mail. Other shipping options are available upon request. I can only ship within the US however. Feel free to ask questions - I will reply promptly. Thanks !
