Here is a very good condition Surplus Shed 127mm f/9.4 (1200mm focal length) lens that I used to build a homemade telescope a couple of years or so ago. (I decided to go back to the f/5.5 version of this lens recently, for wider-field lower-power deep sky views.)

This is a two-element achromat, with a spacer ring between the elements. It's in the metal Wollensak cell that Surplus Shed's recent versions of these lenses have been mounted in, BUT this cell actually marked for the 700mm focal length version. That's why I've taped over the "700" on the cell.

To be clear, this is a 1200mm focal length achromat lens that gives very nice planet and deep sky views (with a narrower field of view than the 700mm version). It's an achromat; expect the usual CA around brighter objects. A filter like a Semi-Apo or similar can help with that.

The back (telescope end) of the lens cell is 5.25 inches inside diameter and threaded, and a shade over 5-11/16ths inches outside diameter.

Surplus Shed now sells these for $249 plus shipping; I'll sell this one for $135 shipped. PayPal (no extra for fee) or money order. CONUS only.

Thanks for looking,
