Coronado PST sun shield

thingiverse

I cobbled together this design in an evening based on some rough measurements of my PST and some educated guessing, all written up in OpenSCAD. It fits neatly behind the filter adjustment ring and blocks the sun's glare from the eyepiece area, making the instrument a lot more comfortable to use and probably easier to operate for afocal photography as well. This design is comparable to many commercial products out there, but you can print it yourself.
