Baader M48 Extension Tube 15 mm

Description

The Baader M48 Extension Tube 15 mm is designed to fine-tune the working distance of cameras and accessories with M48 threads.
On the telescope side, it features an internal M48 thread with 3.5 mm depth, while the camera/eyepiece side includes an external M48 thread with 3 mm depth. Its 15 mm optical length allows precise adjustment for imaging setups.

Made of robust yet lightweight aluminum, it offers a clear inner diameter of 45 mm to preserve the optical field. With a weight of only 0.02 kg, it is compact, durable and reliable.
Following Baader’s modern 3 mm thread depth standard (replacing the old T-2 5 mm), it is fully compatible with modern cameras featuring short optical backfocus.
