Big Bear Solar Observatory

Marv Heilig and Larry Steimle at Costa Mesa testing the Vacuum Solar Telescope

8 inch vacuum solar telescope mounted on main telescope tube.  It had a special Hydrogen Alpha filter and an automatic 35mm film camera for taking Sun photos to use in a space simulator for astronauts.

Haley Mogey made the 8 inch single element lens.  It was a Hydrogen Alpha line telescope (one wavelength), so it didn’t need more than one element.
