Johann Swanepoel's Poster Displays developed for ScopeX 2010  

Johann drove his telescope - the largest home-made telescope ever on display at ScopeX  - 1200km from George to achieve “first light” at ScopeX.  A 20” f/4 in the Krige/Berry style - but with his own unique improvements.

He also developed over time,  and brought along,  a poster display and kindly offered ScopeX these files for download by interested parties:

  • Working On Glass  - Machine grinding, polishing and figuring of large thin telescope mirrors. Footnote:  Doing is better than being paralyzed by design fear problems.     Download Working on Glass.pdf  (900Kb)

  • The Foucault Test – pushing the limits.     Download Foucault Test.pdf (731kb)
  • Dobsonian Design - some design and construction consideration for large aperture telescopes (LAT's).     Download Dobsonian Design.pdf  (1.1Mb)
