FirstLight 90mm Doublet with AZ Mount

The Explore Scientific FirstLight 90mm Doublet Refractor is designed for both beginner and casual astronomers, delivering impressive views of the Moon, planets, star clusters, nebulae, and bright galaxies through a crisp, high-quality 90mm air-spaced doublet lens. With a fast 500mm focal length (f/5.5), it 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 aluminum tripod makes manual tracking smooth and intuitive, and the complete kit includes 9mm and 20mm Kellner eyepieces, red dot finder, erect image diagonal, and smartphone adapter.
