Telescope 1.25" guide camera mount

prusaprinters

<p>A telescope guide camera mount that accepts 1.25" (32mm) diameter cameras such as those from QHYCCD (QHY-5-II and QHY-5-III series) and rebranded ones from Orion. The mount itself is the common dovetail finderscope mount.</p> <p>Required hardware:<br/> 4x M3 hex nuts<br/> 2x M3x20 flat head screws<br/> 2x M3x8 flat head screws<br/> Electrical tape</p> <p>On the C-clamp rings where the limbs meet, the hex nuts fit horizontally, snuggly into capture pockets. You could use a longer screw than the M3x8 here - the extra would poke out.</p> <p>The other hex nuts drop vertically into pockets for securing to the dovetail base. Use a thin strip of electrical tape to 1) provide a cushion to your camera, 2) adjust for printing tolerances, and 3) protect the bolt from poking up and through f you tighten the M3x20 too much.</p> <p>The bottom also has a hole (not threaded) which you can use to screw in tripod adapter plates, as shown in one photo.</p> <p>Cameras shown is a QHY5-III-185C planetary/guiding camera, and the lens is a Fujinon 9mm f1.4 (HF9HA-1B).</p> <h3>Print instructions</h3><p>I printed with GreenGate3d recycled PETG, 0.25mm layer height and a 0.4mm nozzle on my Mk2S. 15% infill. Supports aren't needed - just print the clamps flat (with the nut pockets facing up) and the base with the large flat bottom facing down.</p> <p>PETG is recommended over PLA due to the better flexibility, and PETG can presumably handle nighttime temperatures better.</p>
