Meade ETX Telescope
From Wikipedia, the free encyclopedia
A 105mm diameter Meade ETXThe ETX is a line of Maksutov-Cassegrain telescopes made by Meade Instruments Corporation. They have been produced in diameters of 90mm, 105mm, and 125mm. They are moderately priced compared to other commercialy produced telescopes with their level of performance. Other than Maksutov, another line of ETX based on achromatic refractor telescopes are available in sizes of 60mm and 70mm, but these two models were later replaced by a 80mm model.
“EC” models have provision for automatic control. Older model, called ETX RA, have a clockwork mechanism to track movement of the earth with an equatorial wedge, but it cannot be retrofitted for computer control,.
New ETX telescopes (“AT” models) come with the #497 Autostar controller. This provides “goto” capabilities at an affordable price. (Compare with LX and RC lines of Meade telescopes) Smaller refractor models come with the #494 Autostar controller.
They can be used on a tabletop, or on a field tripod.
