Baader M48 Extension Tube 40mm / 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-/camera side M48 external thread, 3 mm depth
• 40 mm optical path length
• Also used as M48 / 2" nose piece with 36mm insertion depth, safety kerfs and 5 mm 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.
