Celestron sight mount to Picatinny rail adaptor

Simple print, print two pieces and then use very thin double sided tape to help the piece stay in place during mounting and when not in use. Once optics are attached they'll clamp the part down and hold it in place.

No supports required, part cooling fan was used with heated build platform.

Preliminary tests suggest mount is consistent and repeatable. Need clear skies to test further.

SLA printing is not recommended due to how brittle the parts are, PLA might not even be the best plastic and maybe better to use PETG so it has a little bit more “give” in it and better heat tolerance.

Once installed the mount should be roughly 20mm in pitch which puts it in the ballpark for picatinny rails (which are ~21 mm in pitch, or 0.825")

Optic selection:

Mine is a cheap RDS from ebay but the adjustments are pretty meh (the amount of force required to adjust is just stupid strong, it's the other end of the spectrum, the Celestron RDS being a flimsy pile of poo whilst the no-name ebay RDS is way too skoocum for use in astronomy)

I'd suggest a mid-range RDS/reflex sight with sighting adjustments that aren't stiffer then a dead dingo's donga. Preferably one with much more finely adjustable brightness as the ebay RDSes tend to have average to low quality brightness adjustments and tend to be more on the “too bright” side of the spectrum.
