These Accessories work with the SeeStar S50 Pro. Transform your SeeStar Smart Telescope into a powerful tool with AST Core SeeStar Accessories. Protect your glass with a SeeStar lens cap, achieve perfect focus with the bahtinov mask, and experiment with narrow band filtering using the 2" threaded filter holder. All of these items were designed with care in house to work and fit perfectly in your SeeStar S50 Pro Smart Telescope. Each item was carefully engineered to ensure a proper fit as well as a great user experience. The Bahtinov mask was specially designed for the optics of the SeeStar. Using the power of math and engineering we tailored this mask with maximum bahtinoviness. The dew shield is a great dew protector at night. The dew shield fits all of the other accessories. Pro-Tips Solar finding on the SeeStar can be vastly improved by ensuring you perform the levelling process and compass calibration! It is possible to fit all of these accessories (and/or the AST Core Tripod Leveler), inside the original SeeStar Carrying Case! Just carefully fit the Dew Sheild around a Tripod leg, and the rest in the accessory cutout!
