Unlock Enhanced Astrophotography with the Askar 0.6x Reducer for 103APO

Optimized for the Askar 103APO Telescope: Specifically designed to work seamlessly with the Askar 103APO, enhancing its capabilities and performance.
Reduces Focal Ratio to F4: Drastically reduces the focal length to achieve a faster F4 focal ratio, perfect for wide-field astrophotography and capturing expansive star fields.
High-Quality Quadruplet Design: Incorporates a quadruplet lens system that supports a 44mm full-frame image circle, ensuring sharp images across the entire field of view.
Detachable Tube Design: Features a unique detachable tube design, allowing for the necessary back focus adjustments to achieve optimal performance at an F4 focal ratio.
Versatile Adapter Options: Comes with multiple adapter sizes (M681, M540.75, and M48*0.75) at the camera end for easy and flexible connectivity with various camera systems.
Built-in 2-inch Filter Thread: Equipped with a built-in M48*0.75 2-inch filter thread, allowing for direct installation of filters to enhance image quality.
Durable and Precise Construction: CNC machined with metal caps at both ends to protect against dust and ensure long-term reliability.
Weight and Dimensions: Weighs 0.98kg with a standard back focus of 55mm from the M48 thread, maintaining a compact and manageable size for various setups.

The Askar 0.6x Reducer for 103APO is an essential tool for advanced astronomers looking to push the boundaries of their astrophotography, offering unparalleled flexibility and performance enhancements for deep-sky imaging.
