0.4-meter

Las Cumbres Observatory has developed a set of identical 0.4-meter (diameter) telescopes at its Santa Barbara headquarters. These telescopes are wholly modified Meade telescopes with custom equatorial mounts and high-quality CCD cameras. Ten of these telescope have been deployed to LCO observatory nodes: two to Siding Spring Observatory in Australia, one to Sutherland Observatory in South Africa, two to Teide Observatory on Tenerife, two to Cerro Tololo Observatory in Chile, one to McDonald Observatory in Texas, and two to Haleakala Observatory in Hawaii. All of these telescopes are available for science observations. These telescopes are also available for education programs to use. A few hours per semester on these telescopes is reserved for a program to track earth-orbiting satellites.

The 0m4 telescopes are  supported on a C-ring equatorial mount, with all hardware including focus and collimation supplied by LCO. The science instruments on the telescopes are SBIG STX6303 cameras with the following specifications:

  • Mounted at the Cassegrain focus;
  • CCDs with 2048 × 3072 pixels, each 0.57 arcseconds square, for a total Field of View (FoV) of 19 × 29 arcminutes;
  • Default 1x1 binning mode;
  • Readout times < 13 seconds;
  • Single 14-position filter wheel containing Sloan ugriz primed, Johnson/Cousins V & B, and Pan-STARRS w filters.

All 0.4m mounts have the same hardware drive and software control mechanisms with our 1m telescopes.
