The Explore Scientific FirstLight 102mm f/6.5 Achro Refractor Alt-Az Telescope combines power and simplicity to provide new users with a complete observational platform for viewing the moon and planets, and bright deep-sky objects.


Outfitted with a large 4" aperture, it can gather enough light to easily reveal lunar details, pick out Martian icecaps and Saturnian rings, and resolve distant star clusters. Its sturdy rack-and-pinion focuser allows it to handle heavier or awkward loads such as DSLR imaging rigs or the included smartphone adapter, and a larger 40mm drawtube ensures full coverage of camera imaging sensors to avoid vignetting of the view.

The OTA easily attaches to the manual Twilight Nano mount via a Vixen-style dovetail and plate, and with a maximum payload capacity of 14 pounds, it can easily handle the OTA and accessories. Supporting the mount head and OTA is an adjustable-height stainless steel tripod that comes with a center tray to add stability and offers a convenient place to hold accessories such as eyepieces, filters, and adapters. To ensure users can start viewing right out of the box, Explore Scientific includes a 25mm eyepiece, a 90° star diagonal, and a red-dot finder.
