Omegon M48/2″ Adapter
This adapter solves a common practical problem: connecting 2″ accessories to a telescope or optical head with an external M48 thread. Simply fit the adapter onto the M48 thread and you instantly have a standard 2″ output ready for an eyepiece, a filter wheel, or any other compatible accessory. The barrel is secured by a brass compression ring, which holds inserted accessories firmly in place with no risk of slipping.
Optical length and dimensions
The optical length of the adapter is 49 mm. This figure matters when you are calculating the total optical path of your setup - especially if you are working with a camera or using a field corrector. The overall dimensions of 60 x 60 x 49 mm allow compact integration into your optical train without unnecessary extension of the focuser draw tube.
Who is this adapter for?
This adapter suits anyone who needs to bridge the gap between an M48 threaded connection and the standard 2″ format. It is a straightforward solution for astrophotographers planning their optical path and for visual observers who want to use 2″ eyepieces or filters with an M48-threaded device.
