Explore Scientific FirstLight 100mm Mak-Cassegrain with Twilight Nano Mount

This Explore Scientific FirstLight Maksutov Cassegrain telescope is an excellent way to adventure through the night sky with stops to lunar details and to planetary features like those on Saturn and Jupiter. This telescope design is great for visual use to planetary photography. For those wanting to capture the telescopic views with their phone, there is an included Smartphone Camera adapter!

The 100mm aperture and folded optics make this telescope a great tool when it comes to capturing views of deep sky objects without the long and hard to transport design of a Newtonian reflector or refractor with the same focal length.

Twilight Nano Mount and Tripod

This Explore Scientific FirstLight Twilight Nano Alt-Azimuth Mount includes a sturdy steel ST1 tripod with 1.25" diameter legs with a minimum height of 25.5" and a maximum height of 45". Included handle enables smooth movements.

A lightweight alt-azimuth mount and tripod, the Twilight Nano is designed to conveniently accept modest scopes, such as small Mak-Cassegrains, small refractors, small solar scopes, and, naturally, the ED80. Short, fast Newtonians are also suitable for the Explore Scientific Twilight Nano. So long as the weight of your telescope is not over 14 pounds and has a Vixen-style Universal Dovetail bar for mounting the optical tube to the mount head, you are set.


This refracting telescope setup is complete with a smartphone adapter, one 25mm Plossl eyepiece, a red dot viewfinder, and a 1.25" 90° diagonal.
