FS-60CB Fluorite Refractor

The FS-60CB is a 60 mm refractor that employs a multi-coated, two element fluorite objective lens with a prime focal length of 355 mm. This air-spaced doublet has one less light robbing lens than a triplet system and contains no oil between lenses to cloud with age. The true apochromatic optical system delivers virtually perfect color correction, making it ideal for both visual observation and astrophotography. Weighing in at less than three pounds, the FS-60CB is perfect for portable observing, and its modular design accepts optional reducers, extenders, and flatteners to enhance performance for various observing styles.
