The above photo was autoguided on a Meade LX200GPS telescope, which carried the 80 mm refractor.  I also used a violet reduction filter and TeleVue 0.8x flattener/reducer.  K3ccdtools2, version 2.2.4, was the autoguiding program.  A Meade LPI was the autoguiding camera. Photograph made on November 13, 2004.

This image of  the North American nebula in Cygnus required 4 hours of total exposure time.  Tracking was done with a Meade LX200GPS 10-inch scope guided by a webcam, using the program AstroSnap.  This scope carried an ordinary 135mm camera lens piggyback, using Kodak Supra 400 film for a series of four 30-minute shots, which gave the color information.  The Meade also carried a Megrez 80 refractor by William Optics, which used a violet- reduction filter and a TeleVue field flattener (made for the TV 85 refractor).  The Megrez made four 30-minute exposures (simultaneously with the 135mm lens) for the luminance  information.   --Daniel Johnson
