Vince Nettmann hard at work at the Telescope Making Demo Bert van Winsen discusses the intricacies of his 10" scope built for astrophotography. The stepper motor drives are driven by an embedded microprocessor.
Dominic Toldo brought his much-travelled squat 10" Odyssey. It has seen many photons. Tony Golding proudly shows off his beautiful 8", built by Andrew Leigh.
Chris Stewart patiently explains the design of his 6" Dob Enjoying the late afternoon in perfect weather with good company.
Peter Baxter's 10" on a fibreglass fork mount by Hugh Lund. Peter Bosman's 8" Dob sports the first Crayford focuser built in our class. The finish belies the scavenged materials of which it is constructed.
Tony Voorvelt explains radio astronomy Walter Bacchio displaying a small aluminising unit and selling his specially crafted ATM items 
Francois Nortje's 6" on an equatorial platform sports an equipment drawer. Optics & decoration by Lerika Cross. Peter van Laun (centre) shows off his scope on an interesting pier with folding legs. The motor drive worm gear was cut with a threading tap.
Peter Baxter's Beautiful octagonal wooden 6" and his 10" sporting a fibreglass on foam fork mount attracted much attention. Wim van Steenderen's work-in-progress. The mirrors for the 6" binoculars-to-be were figured to within just a few mm of each other in focal length.
The awesome SA-built G6 self-propelled cannon looks like a good basis for a large mobile telescope... Gerhard Koekemoer's scope, computer controlled according to Mel Bartels' design, just keeps on evolving.
Kathy (Mary) McKinnon's 8" was a group effort. It has folding feet that provide a convenient eyepiece height, yet allow it to fit in her car. Case Rijsdijk brought this model of the South African Large Telescope - under construction at Sutherland - all the way from Cape Town. 
Diane "mans" Chris Stewarts 4" on a German mount. The unusual pier was built for stability & portability, for the Lusaka solar eclipse expedition. Keith Lou's experimental minimalist scope is built for travel. It too has evolved over time.
