Coronado PST dovetail mounting plate

thingiverse

I wanted to connect my [Coronado PST](https://www.astroshop.eu/solar-telescopes/coronado-st-40-400-pst-personal-solar-telescope-ota/p,10316) to an [one-armed Dobsonian mount](https://www.astroshop.eu/alt-azimuth-without-goto/omegon-mini-ii-dobsonian-mount/p,53648) in a way, that puts the dovetail into the center of gravity of scope. You need to print the main-body and two clamps. As learned from Prusa, the parts are connected using 4 M3x15 screws and 4 M3sn square nuts. The screws can be longer but should not be shorter than M3x12 (?). The screw-head is optional. I use it as pressure relief, putting it between the mount's metal screw and the printed dovetail. You may also be interested in two alternate designs: * Aaron Turner [thing:3354709](https://www.thingiverse.com/thing:3354709) connects the dovetail to the bottom of the PST. This is perfect, if your have an alt-azimuth mount below the scope. * Vladimir Gorbunov [thing:4570539](https://www.thingiverse.com/thing:4570539) uses the tube of the PST to attach the dovetail. While this has the charm of an adjustable angle, the connection is no longer in the center of gravity of the PST. Clear skys ;-)
