Original Project: 1999 February

The following photos are from my second ATM (Amateur Telescope Making) project. This project was to build 35 (thirty-five) Barn Door Type I tracking platforms. For the complete story see the RASC-KC Barndoor Page and here for the Adobe Acrobat PDF assembly instructions

Each thumbnail (below) is linked to a larger original of approx 100 kb in size. These 35mm slides were scanned at 675dpi at 100% and most are approx 1024x768 resolution as .BMPs then converted to .JPGs using Graphics Workshop for Windows with a Q=80.
