Description
Visual Adapter, 3.5″ to 2″ (for CDK20/24): This adapter slides into the optional 3.5″ Hedrick Focuser. The adapter steps the 3.5″ opening down to 2″ for standard 2″ accessories. The adapter also adds some additional spacing to optimize the use of a 2″ diagonal so focus is reached with most eyepieces.
Buy risk-free: When it’s time to trade up you’ll get the most value for your used gear.
