This item is a 1.25 inch 0.5x focal reducer. I bought it specifically for solar imaging when I was using a QHY5L-II camera on my Coronado Solarmax II 60mm Ha Scope. The problem I was having was that the solar disc would get cut off at the top and bottom of the frame. I purchased this filter and by dropping it into the Coronado diagonal then inserting the QHY5L-II camera above it. The entire solar disc fit in the frame. It worked very well (see attached images). A couple of years ago I got the ZWO ASI174MM camera with the larger sensor and larger pixels, so I no longer need this reducer.

The reducer is in excellent shape, no scratches or marks on the glass or even on the outside of the filter casing. This reducer also comes with a 25mm/1 inch extension. I never used the extension so it is in excellent like new condition as well.

Included are:
one 1.25 inch 0.5x focal reducer
one 1.25 inch 25mm/1 inch extension tube
two plastic end caps

The material looks and feels to be anodized aluminum, but not 100% sure on that.

I attached two images taken while using the filter so you can clearly see the disc fits entirely in the field of view.
