The objective lens of the "Pronto" is an air spaced doublet design where two lenses are matched to work as one. The front element is a positive fluorocrown substitute of Extra-Low Dispersion ("ED") glass; the rear element is of high index flint.

Each lens spherical surface is smoothly polished, and in another testament to Al Nagler's forward thinking - this design can be made well, consistently.

This design allows good color correction and stars appear to snap into focus as intense diamonds against a black velour background - the typical high quality refractor experience.

This telescope is in good  optical and mechanical condition.
