  Our Vacuum Aluminizing chamber comes online
Build from parts scavanged on ebay James Lerch has created a vacuum chamber that will coat
(aluminize) mirrors upto 10 inches in diameter. Positioning the heating elements to ensure an even
coat was one of the difficult parts.

  We snap pictures of asteroid 2002 NY40
Asteroid 2002
NY40 flew past Earth early in the morning on August 17th. It flew by at a distance of 530,000
