Before I knew certain facts I thought I could make a Newtonian scope using an old shaving mirror ( looked very good ) ..I built the ota in balsa wood and used the small mirror you find in toy microscopes to direct light upon the slide as the secondary and an eye piece from the microscope. Looked great and I was so proud until I focused on the Moon and got seven images beside the main one..all rather sharp but I learnt why the mirrors are " back to front".

All this was before I had an interest in astronomy.

However my next scope ( a ten inch with the blank finished but not surfaced) years later was a complete success...I had to build a focuser which worked out well. AND magic views...I built a fork mount with a 1.5 mt polar disk that used car trailer bearings..ok for visual but not perfect.
