Diagonal mirrors and prisms result in images that are correctly oriented up-and-down but reversed left-for-right. For terrestrial observing a fully correctly oriented telescopic image is desirable; the Diagonal Prism accomplishes this image correction and places the eyepiece at a convenient 45° viewing angle. Use with the 1.25" Eyepiece-Holder.

Allows you to use your 35mm SLR for photography. Effectively your telescope becomes your camera lens.

Threads into the front lens cell and effectively inhibits the formation of dew on the lens surface of your ETX-60/70AT telesope.

Colour filters are an essential tool of the lunar and planetary observer, for filters permit the observation and photography of surface detail that is often virtually invisible without filtration.Filters solve, or greatly reduce the effects of, two basic observing problems: (a) Irradiation is the fuzzying of a boundary between lighter and darker areas of the Moon or a planetary surface and can be caused either by the effects of highly con

With Meade AstroFinder software loaded into your PC, Autostar-equipped ETX telescopes may be remotely controlled from your PC display.
