Siderostatic Telescope

This novel telescope design - with an axis aligned to the earth's spin axis - was developed and improved, resulting in the solar telescope behemoths of today. The McMath-Pierce solar telescope, with a focal length of 82-m, at the US National Solar Observatory at Kitt Peak, Arizona, is a good example of this general design. You can find the latest solar images obtained by this telescope here.
