Difference between revisions of "Spider Assembly for Newtonian Telescope (Q54972)"

This thing allows you to precisely position and align the 45 degree secondary mirror on a Newtonian telescope. It is designed around a 1 inch (minor axis) mirror, but you could conceivably use a much larger mirror. The facets on the mirror holder sides make it easy to adjust it's alignment Nov 4 '11- I updated the files for three changes - There are now niches for M3 nuts for the collimation screws. - The main M4 screw now has a conical hole on the angled part, so the part can now pivot, to a limited degree. - Took a chunk off the top of the angles part. Speeds up printing, and makes for better prints.
