Explore FirstLight 102mm f/9.8 Doublet Refractor Telescope with EXOS Nano EQ3 Mount

A 102mm f/9.8 doublet refractor on the EXOS Nano EQ3 German equatorial mount — a complete planetary observation and beginner astrophotography setup with manual slow-motion tracking that follows the sky's rotation. The 102mm achromatic doublet with 1000mm focal length at f/9.8 is optimized for high-contrast planetary and lunar views. The long focal ratio is forgiving of eyepiece quality and produces tight, well-corrected star images. Fully multi-coated optics and a built-in dew shield keep images bright and flare-free. The EXOS Nano EQ3 mount adds what alt-az mounts cannot: once polar-aligned, objects drift out of the field in only one axis, and the dual slow-motion control cables let you make precise corrections with a light touch. This makes high-magnification planetary observation far more comfortable and opens the door to smartphone astrophotography with longer exposures. Key Features 102mm f/9.8 achromatic doublet, fully multi-coated EXOS Nano EQ3 German equatorial mount (15 lb capacity) Dual slow-motion control cables for precise tracking 2.5 lb counterweight, stainless steel tripod (25.5"–45") 25mm Plossl eyepiece, 90° diagonal, red-dot finder Smartphone camera adapter included Ideal For Planetary and lunar observers — the EQ mount keeps objects centered at high magnification far longer than an alt-az mount Beginner astrophotographers — equatorial tracking enables longer smartphone exposures without star trails Observers planning to grow — the EQ3 mount accepts motorized tracking upgrades
