Extender tubes (2" or 1,25")

If the focuser outward travel seems to be insufficient to reach focus, an extension tube is needed.

More about the product

When using a refracting telescope without Amici-prism or diagonal most probably an extension tube needs to be fit into the focuser to reach the focal plane. The 2z35, 2z50, 2z80 adaptors are for 2" focusers, while 1z26 and 1z37 adaptors are for 1,25" size with different lengths, depending on the model.

M56M5660 is for SkyWatcher focusers only, it extends the focuser tube by 60mm. Extremely massive.
