Sony E-Mount 1.25" Telescope Adapter

Single-piece adapter for mounting a Sony E-Mount camera to a 1.25" tube (e.g. insert directly into star diagonal)

Thanks to this model/designer for the e-mount geometry.

Designed for and tested with a Sony a6000 and Celestron NexStar 5SE, but should work with most E-Mount cameras and telescopes with 1.25" optics.

• I used PETG, but I'm sure PLA will work too.
• Print with the tube face down (as positioned in the file)
• Supports should not be needed
• Use ironing to make the surfaces that mate against the camera as smooth as possible.
• Take advantage of variable layer heights to reduce print time (the main tube is just a plain cylinder, which can use a larger layer height. But the mount side should be as precise as possible)
• Post-processing: Be sure to thoroughly clean up any stringing, dangling bits of filament, etc. You don't want little pieces of plastic getting into your camera or telescope optics

See 3mf for my print settings. I used black Prusament PETG.
