Explore Scientific FirstLight 90mm Doublet Refractor Telescope with AZ Mount
Start your journey through the cosmos with the Explore Scientific FirstLight 90mm Doublet Refractor Telescope. Designed for both beginner and casual astronomers, this telescope delivers impressive views of the Moon, planets, star clusters, nebulae, and even bright galaxies—all through a crisp, high-quality 90mm air-spaced doublet lens. With a fast 500mm focal length (f/5.5), the FirstLight 90mm provides wide-field views ideal for scanning the night sky and capturing rich detail. The air-spaced doublet optical design minimizes chromatic aberration, while fully multi-coated optics ensure bright, contrast-rich images. Its simple alt-azimuth yoke mount with altitude rod makes manual tracking smooth and intuitive, and the full-size aluminum tripod offers stability and a convenient accessory tray. The included 9mm and 20mm Kellner eyepieces, red dot finder, erect image diagonal, and smartphone adapter make this kit a complete, ready-to-use system for day or night observing.
