The Meade ETX-125EC telescope is a Maksutov-Cassegrain design that folds a relatively long focal length into a relatively short and easy to handle optical tube. The long focal length makes it easy to reach high magnification for observation of the moon and planets. The 125 mm aperature is large enough for nice views of brighter deep sky objects. The Meade AutoStar controller provides Go-To operation (Note that this AutoStar computer is an older generation and setup takes a bit of time, but it works fine for viewing the moon, the planets, and some brighter, easier to locate deep sky objects.)


Meade ETX-125EC Specifications

  • 127 mm (5") aperture Maksutov-Cassegrain optics, 1900 mm focal length.
  • 40 mm Eyepiece provides 48x magnification and a 0.8 Degree Field of View
    • This eyepiece gives the widest field of view and is the best one to use for finding objects
  • 26 mm Eyepiece provides 73x magnification and a 0.7 Degree Field of View
    • This eyepiece will give nice views of the entire moon and large deep sky objects
  • 9 mm Eyepiece provides 211x and a 0.6 mm exit pupil
    • This eyepiece gives the maximum recommended magnification under perfect conditions
  • Internally powered by 8 (user-supplied) AA batteries which will run it for approximately 20 hours under normal usage.
  • AutoStar hand controller with large object library provides Go-To operation (Note that this AutoStar computer is an older generation but works fine for viewing the moon and planets.)
  • Field tripod.


Note: This telescope was recently serviced by Bob Mulford, an SAS member.  Here are his notes on the telescope:

This Meade ETX-125EC is not as easy to use as many of today's scopes. The ETX series was introduced in 1996 and the electronics, at least on the older model like this one, are not nearly as sophisticated as modern offerings.  The alignment requires several steps including leveling the mount, leveling the scope, and finding north. I did this alignment process reasonably carefully, but did use some shortcuts that I think beginners might use, and while the GoTo system pointing was always close, it was not always close enough to put the sought object, including alignment stars, in the field of view. Also, the the field of view at the lowest magnification (48x) is less than one degree, and therefore this telescope needs to be rather precisely pointed in order to acquire an object for viewing. Still, I was able to use it effectively.
