0.965 to 1.25 eyepiece adapter for star diagonal

thingiverse

This is for adapting an older telescope's 0.965" star diagonal to fit more modern 1.25" eyepieces. To use, unthread the 0.965" eyepiece receiver from the diagonal, and replace with this piece. The advantage of using this over a standard adapter is that the light path is shorter so you have more inward focus available. On my vintage F15, this was required to achieve focus on stars. I would recommend printing this threaded side up with supports where touching the buildplate only.
