Cooler NT-12

Cooler NT-12 - Newton 12" telescope cooling system

Cover for telescope mirror cooling.

The problem of thermal stabilization of telescope optics is familiar to many amateurs of astronomy. The lens of the telescope, only taken out for observation from a warm room or the car's interior, cools down for a long time to the temperature of the surrounding air. Above the surface of mirrors there is a boundary layer of warm air, and ascending streams rise along the pipe. All this spoils the picture, especially at high magnification. With a temperature drop of 10-15 °, the main mirror of a large telescope can cool down to several hours, making it impossible for qualitative observations. The problem is solved by installing active cooling for optics.

The cover on the rim of the main mirror Cooler NT is equipped with a powerful blower blower.The included cooler creates a low-pressure zone around the main mirror and, due to this, the air inside the pipe starts to blow out the front surface of the main mirror.This blowing solution is solved immediately by two problems: it allows you to get rid of convective currents rising along the pipe walls and blow off the boundary layer of warm air, and also to speed up the process of cooling the mirror to the air temperature. The Cooler NT line is fully compatible with Newton's 6 ", 8", 10 "and 12" telescopes manufactured by Synta (trademarks: Sky-Watcher, Celestron, Orion, Meade, Konus, Levenhuk, Arsenal and analogues). In the two younger models for 6 "and 8" telescopes, attachment of the attachment to the frame takes place with the help of special pivot feet, and in the older 10 "- the cover panel is screwed to the regular threaded holes in the movable part of the frame.
