EQUINOX 80 OTA
The Equinox 80 is another excellent choice for birding, nature study, and photography. Its fast, high-contrast optics and generous field of view make it an ideal instrument for studying larger clusters and star fields, and it is a proven performer for astrophotography – you can even use it with a common SCT focal reducer to achieve speeds down to f/4.5! But don’t be afraid to push up the magnification, too. Its crisp optics make it a strong performer on tight double stars, and it provides crisp, clear lunar and planetary images with no image breakdown, even at 150x.

EQUINOX 100 OTA
The Equinox 100 departs slightly from the other refractors in this series. It is designed primarily as a visual instrument for high-power, high-resolution applications. The Equinox 100 features a beautifully corrected ED doublet with a focal length of 900 mm. It provides outstanding views of solar system objects and of brighter DSOs, and can split even the tightest doubles with ease. For added fun, attach a video camera along with our 2” ED 2x Barlow and treat yourself to stunning real-time views of earth’s nearest neighbors!

EQUINOX 120 OTA
The Equinox 120 is the star
of the Equinox Series. Its generous aperture makes it an ideal observing
instrument for solar system and deep space objects alike – and it really
shines on double stars. For astrophotography, the Equinox 120 features an f/7.5
focal ratio – more than speedy enough for today’s sensitive CCDs and digital
SLR cameras. Plus, it can be coupled with a common SCT focal reducer to achieve
even faster speeds.Its high-power views are stunning.
For experienced observers and novices alike, the Equinox 120 delivers remarkable
and memorable views. It has the perfect configuration of aperture, focal length
and focal ratio to make it a general-purpose telescope that can be used for
everything from widefield viewing to high-power planetary imaging. It may be the
only telescope you will ever need, and one of the finest you will ever look
through in this aperture class.
