Skywatcher ED80 with binoviewer ?

[NGC 1502]

I have an early version of the Skywatcher ED80 and have the chance of buying a used William Optics Binoviewer.

I’ve searched online to find relevant info on combining the ED80 and WO Binoviewer.  The purpose will be for low power use only, therefore I don’t want to add a barlow to achieve focus.

However I’m thinking I could shorten the tube to allow focus without a barlow.  It should be a simple job in principle to remove the focuser and cut the tube.  The focuser isn’t threaded on, just 3 screws.  I’ve read that this could vignette a low power view if tube baffles are not removed.   I have both 1.25” and 2 inch diagonals.

Has anyone reading this ever tried it and do you have any hints and tips, or any thoughts?
 

Thanks very much in advance 👍
