Explore Scientific 8-Inch Dobsonian Reflector Telescope
$549.99
A Powerhouse 8-Inch Dobsonian for Deep-Sky Exploration
This 8-inch Newtonian reflector is a powerhouse for deep-sky exploration and astrophotography. A large 208mm primary mirror pulls in significantly more light than smaller scopes, revealing fainter nebulae, star clusters, and galaxies.
A fast f/5.9 focal ratio keeps exposure times short for astrophotography while still delivering bright, detailed views for visual observation.
The Dobsonian mount's spring tension system makes for stable, intuitive operation at any experience level, and the scope arrives with an eyepiece, finder, and smartphone adapter ready to go right out of the box.
