Baader M48 extension tube 30 mm / 2" nosepiece with Safety Kerfs

• Used to adjust the working distance of larger cameras and similar accessories with M48 thread
• Telescope side M48 internal thread, 3.5 mm depth
• Eyepiece side M48 external thread, 3 mm depth
• 30 mm optical path length
• Also used as M48 / 2" nose piece with 26 mm insertion depth, safety kerfs and 5mm optical height

Modern cameras are usually characterised by extremely short optical heights, in order to be able to be mounted on various telescope constructions. The old T-2 standard with 5mm thread depth is a hindrance to this. To take care of this new development, all new Baader T-2 and M48 parts are delivered with the new 3 mm standard.
