Orion Starblast 4.5 / 114mm telescope tube baffles
thingiverse
Internal baffles for the Orion Starblast 4.5 / 114mm telescope. This will fit any OTA with an **external tube diameter of 140mm**, made of 0.5mm thick steel. Print using a matte black filament, like the MatteForge, with a 0.3mm layer height, upside-down and without brim. Insert from the bottom, with the pegs oriented to the back. On my highly modded OTA, I've used 6 of those : 5 with 3cm pegs, and a 6cm version close to the mirror cell, as it's been moved forward in the astrophotography conversion. EDIT : New 2018/01/15 : a front baffle that goes in front of the spider vanes Time lapse : https://www.youtube.com/watch?v=f61Fsq-Ofvs and a second one, printed on a raft : https://www.youtube.com/watch?v=3gFMI0qkw5E
