Custer Equipment

Custer has a large collection of telescopes of all sizes and description.
Equipment in BOLD are those most often used. Among them are:

  • 10" Zerochromat refracting telescope. It is the largest of its type in the United States. This is in the main observatory dome.
  •    Our 10” refracting telescope was manufactured in England by Zerochromat Telescopes. Designed by award-wining optician Peter Wise, the telescope’s unique dialyte lenses make it apochromatic, providing superior views of solar system and deep space objects. The folded light path construction uses mirrors to make the telescope a manageable size (still more than 6’ long), allowing the long f/12 focal length telescope to fit in our dome.
       The telescope is attached to a computer-controlled Fornax 152 equatorial mount, permitting easy aiming and object tracking. The entire assembly can be raised/lowered on the Pier-Tech pier to accommodate most users’ heights, for comfortable viewing. Custer’s Zerochromat telescope is the largest of its type in the United States.
