I've just upgraded my eyepieces/diagonal to 2" components and am finding it difficult get a focused image. Through trial and error it seems that if I just barely insert both the eyepiece and the diagonal nosepiece into their respective clicklocks then I'm able to focus the image; however this does not feel like the eyepieces are secure. This leads me to believe an extension tube may be required; is this component compatible with the Baader 2" Clicklock diagonal, and would it provide an extension versus the standard nosepiece that comes with the diagonal? It there a different piece I could install to extend the eyepiece side of the optical train instead of between the SCT and the diagonal? Thanks!

My setup, for reference:

Description

Details

Modern cameras are usually characterised by extremely short optical heights, in order to be able to be mounted on various telescope constructions. The old T-2 standard with 5 mm thread depth is a hindrance to this. To take care of this new development, all new Baader T-2 and M48 parts are delivered with the new 3 mm standard.
