Looks like I am running out of options but one last try - if anyone has a big'ish refractor they might consider selling please send me a PM.
Basically I would be interested in anything over roughly 110mm, preferably a doublet and better than a standard achro. As a few ideas any of the following spring to mind but if you have something else I would certainly welcome the offer. Thank you for looking at my post
Skywatcher BD120 or earlier gold tube version
Orion 120 Equinox
WO Megrez 120
Vixen ED115
or even a Vixen NA140
