Solar Filter for Celestron StarSense Explorer 10" Dobdonian

DO NOT OBSERVE THE SUN WITHOUT PROPER PRECAUTIONS!

Make sure you're using a safe filter. Ensure the filter and the aperture reducer cover is secure to the telescope, otherwise you risk damaging your camera, telescope, or your eyesight.

This is an original Design using onshape. (my First!) I did get inspiration from the “Telescope Solar Filter Adapter” from ZCraftworks. The diameter was not going to fit my telescope so I had to design my own. I decided to completely sandwich the film between the top and bottom parts for increased safety. I also made the outside round to cut the filter around the outside of the frame after assembly.  And finally, I put a flange on the top to store the dust cap on the filter so the filter can be stored on the aperture even when not in use.

This adapter was designed to fit over the offset reduced aperture of (57.5mm) for a Celestron StarSense Explorer 10” Dobsonian.

The three cover configuration pictures show the cover as a normal dust cover, moon/planets, and solar. all configurations store the aperture cover.

Cut a solar filter to a diameter of 75 mm. I used the one below from Thousand Oaks Optical.

Install heat set inserts with a soldering iron, place filter in the adapter, use a crosshead screwdriver to punch the screw holes in the filter and screw lid on top with five M3-8mm screws.
