A complete 90mm doublet refractor telescope kit with a yoke-style alt-az mount, tripod, and two eyepieces — everything a beginner needs to start observing the Moon, planets, and bright deep-sky objects at the lowest entry price in the FirstLight lineup.

The 90mm air-spaced doublet objective gathers enough light to show lunar craters, Saturn's rings, and Jupiter's cloud belts. The erect-image diagonal delivers correctly oriented views for daytime terrestrial use as well. Two Kellner eyepieces (9mm and 20mm) provide low and high magnification out of the box.

The yoke-style alt-az mount moves smoothly up/down and left/right with no alignment required — just point and look. The full-size aluminum tripod with accessory tray sets up in under a minute.
