Key Features:

• Designed for use in GSO Ritchey-Chretien and compatible RC telescopes.
• Reduces the effective focal length of the telescope by 0.75x.
• Converts an f/8 scope to f/6 or an f/9 scope to f/6.75, enhancing astrophotography capabilities.
• Carefully crafted with two-element fully multi-coated optics to maintain image color, brightness, and contrast.
• Retains the inherent field flatness of an RC scope, although it does not function as a field flattener.
• Ideal for astronomy cameras with sensor diagonals up to 15mm.
• Provides approximately 80mm of back focus, accommodating off-axis guiders and filter wheels.
• Features a black-anodized body that fits into a 2” focuser or adapter, securing accessories with 2” barrels using a non-marring compression ring.
