I just finished restoring an old Cave 10" f/6 newtonian. Works great for visual purposes. My concern is that after the restoration the 'rack and pinion' focusing tube required a short extension in order for it to be able to bring things into focus, and now if I have to add any instrumentation, e.g. CCD etc., we're now about 3-4 inches away from the tube. Is there any way to support the focusing tube so it can handle the extra weight in this postion or would you consider replacing the whole tube so it can bring the focus closer in or both. The optics are perfectly collimated now.
Thanks!
