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!

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.
