Telescope, Primary and Secondary Mirror

thingiverse

6-in Dobsonian Telescope- made for viewing the moon up close. 31 mm secondary mirror The primary mirror design is out-dated; Working on a new configuration that makes it easier to line up mirrors. Used a concrete cardboard tube which I strengthened by doing a fiberglass layup over top of it. The concrete tube tolerances were much to large to make a well functioning telescope. Going to create a new design that uses steel rods rather than concrete tube. Will make sure that everything is off the shelf or 3D printable, no machining required to build. Telescope stand was built using a lazy susan and several pieces of MDF. The link below was used for inspiration: https://www.youtube.com/watch?v=f27s0_S6E0E Improvements to be made: - Better aligning system - 2 aligning springs - Tube with tighter tolerance - More robust tube balancing and telescope stand Will post more details when build works.
