Hi All,

I have just purchased an EdgeHD 9.25 and focal reducer and have been grappling with image quality issues when using the focal reducer.

Tonight, I did a test with and without the FR and I noticed that the focus point between the 2 configs is about 15-20 turns of the focus know different.

So, if I focus at F10 the add in the FR I have move the focus knob CCW about 15-20 turns to get focus.

Is this right? I would think that the focus point should be roughly the same.

I notice that with the FR I get heaps of curvature and elongated stars all over the place.
