Baader Planetarium 2" Safety Kerf Nosepiece with 2" Filter Thread

This is an ultra hard 2" nose piece which as Baader's proprietary Safety Kerfs, introduced in the Morpheus and Hyperion Zoom Mark IV eyepieces, machined into the barrel. The numerous shallow kerfs give additional grip and security from inadvertent slipping, without the annoying problems sometimes caused by traditional deep undercuts.
