76/300 Pocket Dobson: a tiny yet real telescope that comes with you everywhere

A “relaxation” project, mostly drawn on planes to and from Norway this month, where I had to travel to setup a digital art installation in Kristiansand with friends from the digital art collective Lab212. It has been drawn with one major constraint: it must fit in the inner pocket of my jacket (well, one specific jacket), except for the rods.

This is a 3D-printed dobsonian telescope built around a 76mm/300mm parabolic mirror kit. While there are plenty of mini-scope models on the internet, I wanted something that looked like a dobson that went a bit too hard through the clothes dryer, but without compromise on what matters:

Balance Smooth movements Rigidity Collimatable Focusable eyepiece holder A minimum of style (entirely subjective)
