Explore Scientific 8” f/3.9 Carbon Fiber Newtonian OTA -
This fast f/3.9 8” Newtonian from Explore Scientific is great for astrophotography! The Explore 208 mm Newtonian has a faster f/ratio than most 8” imaging reflectors on the market today at f/4. With faster optics, you’ll be able to get a deeper shot without increasing exposure times.
The primary mirror is topped with 97% reflectivity EMD coatings, and the no-tool, 3-point, push-pull collimatable secondary mirror holder adjustments and no tool adjustments for the "clipless" primary mirror holder cell have locks so the optics stay aligned and produce the best images. The OTA is made of Carbon Fiber, for good looks, a lighter weight compared to aluminum, and virtually non-existent focus drift during longer exposures.
Accessories include a 2” Two Speed Rack & Pinion focuser with 10:1 reduction and a 50mm Extension Tube and 1.25" Adapter. It also has Cradle Rings with a built-in handle, a Vixen-style dovetail, and a soft carry case. A finderscope base is attached to the OTA, but the bracket and finder are sold separately.
