  1. Millenium Telescope. Initial Meeting.

  2. Format Part 1 - Planning Part 2 - Sample Designs Part 3 - Discussion/what happens next

  3. Objectives • Resolve location and usage issues • Agree design • Present detailed design/cost to Committee • Go/No Go?

  4. Aperture Fever…!

  5. Part 1 - Planning...

  6. Location/usage Most difficult part! Dedicated effort Some options • Dome • Balcony • Downstairs • Elsewhere in school grounds

  7. Design Goals • Ease of construction • Ease of assembly/disassembly • Ease of storage and transportation • Ease of collimation (repeatable)

  8. Mirrors Primary Mirror (Pyrex): • Diameter, 482 mm • Edge thickness, 38 mm • Focal length, 2165 mm (F/4.5) • Calculated weight 15 Kg Secondary Mirror (elliptical plate glass): • Major axis, 150 mm • Minor axis, 106 mm • Thickness, 14.5 mm
