Bought this to replace the 1.25" to 2" adapter on a stock Startravel 120 focuser.

I had already replaced the 45 degree prism diagonal with a 90 degree mirror diagonal and added a heavy Baader eyepiece in place of the stock 10mm / 25mm eyepieces that come with the scope.

The new train, and any subsequent train additions I might accumulate in the future we just a bit loose in the stock 1.25" to 2" adaptor, this new adaptor, although I've not had weather to put it to use, make the train a far firmer fit, and the grasping mechanism is less likely to damage or impinge on the diagonal.

At the time it was a toss up between completely changing the focuser for the Crayford type (which looks to have a better adaptor, or just get this for the time being).

I'm pretty happy for what it is, arrived quickly even by 1st Class Royal Mail.

really the item was very good .

This adaptor from BAADER is a fantastic..
It securely keeps my 1.25" Tak diagonal SECURE AT ANY ANGLE even with heavy EPs Highly recommended if you don't want your precious EPs falling out and in focus position always!
