Explore Scientific Extension Ring Set M48x0.75 - 5 pieces

Five extension tubes from 30 to 5mm length with thread connection M48x0,75mm in a set

For adjusting different distances of the camera to the focal plane of the telescope or the corrector/field flattener. There is an M48.0,75 internal and external thread in each individual tube. The M48x0.75 thread is also called large T2 photo thread or 2.0 inch filter thread. Camera specific bayonet adapters or color and nebula filters can be used.

Included are 5 different tubes with the steps 30, 20, 15, 10 and 5 mm. The larger free inner diameter of 45.0 mm effectively prevents undesired vignetting of the camera sensor. The outer diameter of the sleeves is exactly 50.65 mm and can therefore be mounted directly in any 2 inch diameter eyepiece adapter.
