However, instead of being oriented up and down, it is tilted at the same angle as the Earth's axis of rotation. The equatorial mount also has two perpendicular axes of rotation - right ascension and declination. This makes this type of mount useless for taking photographs of the stars. The zig-zag motion in the figure above is exaggerated and simplified for purposes of illustration actually there would be more steps, and each step would be smaller. In trying to follow the motion of a star, the mount produces a "zig-zag" motion, instead of a smooth arc across the sky. 13,469 telescope drawing stock photos, vectors, and illustrations are available royalty-free.

It provides good support for a heavy telescope, as well as smooth, frictionless motion. This mount is usually used on Dobsonian telescopes. You can find more Telescope Drawing in our search box. Twenty two artists were selected nationwide to attend the James Webb Space Telescope Artist Event at NASAs Goddard Space Flight Center in Greenbelt, Md. rocker box - a low center-of-gravity box mount, usually made of plywood, with a horizontal circular base (azimuth axis) and Teflon bearings for the altitude axis. We have collected 38+ original and carefully picked Telescope Drawing in one place. NSFs NOIRLab (NSFs National Optical-Infrared Astronomy Research Laboratory) is the US national center for ground-based, nighttime optical astronomy.It has a ball shaped end that can rotate freely in the socket mount.
