As Ken has stated, a 2" diagonal adds a significant amount to the light path & there isn't much you can do.

However, depending on how much inwards travel you need to get to focus you may have one option. If you are extremely close to the focus point when your focuser is racked all the way in then you might look at the Televue in-travel adapter.

This is essentially a 2" adapter you put on the eyepiece which has a 5mm well at the top. This will move your eyepiece a further 5mm inwards with respect to the light path which, depending on how close to focus you are, may allow your eyepiece to come to focus.

If you require more than 5mm more in-travel then, I'm afraid there are no other options that I'm aware of.

Hope this helps
