I am looking for a refractor to bridge the gap between my binoculars and my 12" Dob for use as an RFT scope for personal use and for outreach. If I get more than one good offer I will probably also purchase a unit for our college's Astronomy Class.

After much pondering, I think I want an Achromat with an aperture of between about 110mm and 130mm (maybe up to 150mm), at F5 or thereabouts. An ST120 or similar would probably be ideal, though I am certainly open to other scopes of that general type. ATM solutions are also acceptable if they have good build quality. It will probably end up mounted on a CG-5 mount.

My priorities are for a TFOV around 4 degrees (so 2" focuser essential), optical quality adequate to split moderate doubles and sufficient aperture to see some basic DSO's (veil, M81/82 etc etc) though I have other scopes I will be using for deeper DSO observing. I am a visual observer and don't envisage doing any AP. Optics should be in very good condition or better; I'm much less worried about cosmetics.

I have a nominal budget of about $350 shipped to 87571, though I am not beyond tempting a tad higher if a particularly good scope comes along.

Please let me know what you have and what your scope comes with (Rings? Diagonal? Finder? CA Filters?)
