Starboosa Telescope Extension Tube Kit for Cameras and eyepieces
The 2" extension tube kit is used to obtain the correct image focal length or exact spacing required, thereby solving the spacing problem in astrophotography.
The required spacing can be achieved by combining several extenders of differing lengths;you can use 1 piece;2 pieces of the extension rings as you like.
The M48x0.75 threads on both ends make it versatile. External thread M48 * 0.75; internal thread M48 * 0.75; a series of focusing problems are eliminated.
By combining multiple extenders of different lengths, you get the right focal length to focus with the camera or eyepiece.
All metal construction and anodizing aluminium process;durable for long time use.
