A heliometer (from Greek 'sun' and 'measure') is an instrument originally developed from the mid-eighteenth to early nineteenth centuries for measuring the variation of the Sun's diameter at different seasons of the year, but the modern version of the instrument is capable of much wide

thumb|Christoph Scheiner's Helioscope A helioscope is an instrument used in observing the Sun and sunspots. The helioscope was first used by Benedetto Castelli (1578–1643) and refined by Galileo Galilei (1564–1642). The method involves projecting an image of the sun onto a white sheet of paper suspended in a darkened room with the use of a telescope.

A spectrohelioscope is a type of solar telescope designed by George Ellery Hale in 1924 to allow the Sun to be viewed in a selected wavelength of light. The name comes from Latin- and Greek-based words: "Spectro," referring to the optical spectrum, "helio," referring to the Sun, and "scope," as in telescope.

telescope that operates autonomously

telescope with mirror made of a reflective liquid

very long focal length refracting telescope without a tube, built in the 17th century; the objective was mounted on a pole, tree, etc. on a swivel ball-joint; the observer stood on the ground and maneuvered the eyepiece to aim at celestial objects
