CA Residents: Prop 65 Warning(s)

Sky-Watcher's Evostar apochromatic doublet refractors offer an ideal fusion of top-tier extra-low dispersion glass and budget-friendly pricing. The refractor lens assembly, featuring a unique combination of precisely matched lenses, ensures razor-sharp stars against a backdrop of deep, rich skies. Crafted with fluorite-based ED glass elements and enhanced by Metallic High-Transmission Coatings™ (MHTC™), these refractors virtually eliminate false color, while the triple-baffle design prevents stray light interference for impeccable photography results. The telescope's tube, made from aluminum and adorned with a sleek black diamond metal-flake finish, adds a touch of elegance to its exceptional functionality.

Opting for a doublet refractor presents distinct advantages. The reduced amount of glass translates to a lighter telescope, resulting in a more affordable option. This allows you to allocate more resources towards enhancing your astrophotography setup, whether it be investing in a high-quality camera or upgrading your laptop.

The Evostar 100ED arrives in a foam-lined aluminum case, fully equipped with essential accessories. These include a 2-inch Crayford-style focuser, a 2-inch dielectric diagonal, two 1.25-inch eyepieces (5mm and 25mm), an 8x50 right-angle finderscope, tube rings, and a V-style dovetail. Elevate your astronomical experience with this comprehensive and meticulously designed telescope package.
