William Optics Mini RedCat 51 - 51 mm f/3.5 WIFD Refractor - L-MC51RD

Embark on an amazingly wide field astronomical journey with the latest rendition of the William Optics RedCat - the Mini RedCat 51! This compact 6-element apochromatic refractor telescope merges cutting-edge technology with user-friendly features, making it an ideal choice for both budding astronomers and seasoned astrophotographers. With its sleek, robust design and innovative optical system, the MiniRedcat 51 WIFD delivers crystal-clear, vibrant images, capturing the splendor of the cosmos with ease and precision.

Highlights:

• Exceptional Optical Quality: Boasting a Petzval-like optical design with 6 elements in 2 groups (two of which are super ED!) and a crazy fast f/3.5 focal ratio, this telescope offers sharp, detailed views across an extremely wide field of view!  With an image circle of 43.2 mm, astrophotographers can fully illuminate even full frame sensors and capture super expansive objects beautifully without worrying about back focus!  

• Durability Meets Portability: Crafted from CNC-machined aluminum, the Mini Redcat 51 provides durability without sacrificing portability, ensuring it’s always ready for your next adventure under the stars. This system comes with a camera rotator, Synta-type handle, Bahtinov mask for focus assistance stored in the lens cap, rings and dovetail!

• WIFD Advanced Focusing System: The state-of-the-art WIFD focuser allows for fine control, significantly enhancing image clarity for both visual and photographic pursuits.  The movement of the WIFD (Williams Internal Focus Design) focuser is integrated inside the main tube assembly for a movement & tilt-free experience.  

The precise internal sliding of fixed optics prevents image shift.  The integrated position viewing window on the focuser provides instant verification of the graduated numerical display.  The smooth rack and pinion design is incorporated into the focuser to provide super fine adjustability for critical focus.  The internal movement of the optical elements is protected from inclement weather and environmental issues like dust and pollen and can’t come out of alignment.  The redistribution of weight allows for better balance during imaging sessions.

• Versatile Camera Compatibility: Designed to connect seamlessly with a variety of cameras (including Full Frame!) and astrophotography accessories, including the EAF, or Electronic Auto Focuser, the Mini Redcat 51 is a versatile tool for capturing the universe.
