Coronado PST sun shield

thingiverse

Something I threw together in an evening based on some measurements of a my PST and some guess-work, written up in OpenSCAD It fits behind the filter adjustment ring and blocks the glare of the sun from the eyepiece area, making the instrument much more comfortable to use and probably easier to use for afocal photography as well. This is comparable to many commercial products you can find, but you can print it yourself.
