A 102mm f/6.5 doublet refractor on the Twilight Nano alt-az mount — the largest refractor in the FirstLight Twilight Nano lineup, offering more light-gathering and resolving power than the 80mm while keeping the same grab-and-go simplicity.

The 102mm aperture pulls in 63% more light than an 80mm, revealing finer detail on planets and bringing fainter deep-sky objects into view. The 660mm focal length at f/6.5 produces wide true fields, making it easy to find and frame targets. Fully multi-coated optics and a built-in dew shield round out the optical package.

The Twilight Nano mount's panhandle control tracks objects smoothly, and the stainless steel tripod adjusts from 25.5" to 45" with a 15 lb capacity.
