[UniPol]

Yep, that's exactly what I've done with one of my Unitron 4" pier mounted photo equatorial 132E refractors from the early 1960's. It takes up virtually no floor space at the top of the stairwell. Note that my Unitron is fitted with a Bintel 2" Crayford focusser which was fitted just to try out modern eyepieces. No mods to the tube were needed so the Unitron focusser can be refitted to keep it original. This particular pier model is fitted with a weight driven clock drive much nicer than an electric one.
