Explore Scientific FirstLight 152mm Doublet Refractor
with EXOS2GT GoTo Mount

This Explore Scientific FirstLight GoTo refractor is sure to help as amateur astronomers explore the solar system and deep sky through their telescope. This setup comes with a sturdy mount, a tripod, a Plossl eyepiece, a red dot finder, and two 11lb counterweights. With all of these accessories, the telescope can almost be used directly out of the box.

The 152mm aperture is great for capturing views of deep sky objects and the doublet design, a pair of glass lenses separated by a cushion of air, minimizes chromatic aberrations.

EXOS2GT GoTo Mount

The EXOS2GT mount is a German equatorial mount equipped with GoTo technology. Motors are equipped on both axes which allow the mount to move smoothly and accurately as it tracks astronomical objects. The precision gears allow for minimum backlash on all nine of the mount's slew speeds.

This mount only needs a simple 1, 2, or 3 star alignment to orient the scope.


The included tripod is a 1" stainless steel tube tripod and has an accessory tray that can be used to hold eyepieces and other accessories while observing. The accessory tray also enhances the stability of the tripod.

Included Accessories

This refracting telescope setup is complete with a smartphone adapter, one 25mm Plossl eyepiece, a red dot viewfinder, downloadable software (follow the link below), a 2" 90° diagonal, and a built-in dew shield to slow moisture build up on the objective lends and ambient light interference.
