Works well.
Adapts from female T2 (such as inside of ASI camera (not mini)) to male C thread which I have on my Alpy 600 spectrometer.

I have number of good lenses that are all C-mount and this adapter means I can use them with my ZWO ASI120MM-S.
Good quality and finish. Brings lenses to good focus. Perfect.

Got this adapter for my little chinese knock off wide angle lens. Works like a charm, thumbs up for quick delivery and No1 service from FLO.

Bought to connect guide camera to alpy guiding module. Excellent product, well made at half the price of the adaptor from Shelyak. Great service to from FLO

As it's just an adapter, there's not a lot that one can say except that it's well made and works. Mine is ussed to couple ATIK GP camera to Alpy 600 guide port.
