AC623 1.25" to 2" off-axis eyepiece adaptor

£32.99 including UK P&P

From a side view this adaptor looks like a standard 1.25" to 2" eyepiece adaptor ­ but from above or below things look very different! The off-axis positioning of the 1.25" hole is designed to allow CCD auto-guiders (or other cameras) to be rotated in the 2" eyepiece holder and progressively sample the whole 2" eyepiece field rather than just the centre.

Normally if your auto-guider scope is supported in rings, you would need to either fiddle with the rings or change the primary scope´s pointing position ­ not very convenient. This simple modification to a standard adaptor lets you easily investigate the whole field of view of your scope by simply rotating the adaptor ­ very convenient. Surprisingly the adaptor allows nearly 16mm of lateral movement across the field. Obviously this product is only suitable for use with scopes fitted with a 2" focuser. The off-axis adaptor has two brass chrome-plated lock screws, and is supplied with an additional two hard nylon thumb screws to allow greater slippage control if required.

The adaptor nosepiece has an anti-slip recess and is threaded for standard 2" filters. The adaptor is CNC precision-machined from aluminium and has a black anodised finish.
