2016/11/10 Still Struggling ...

Received a new reducer/rotator design (super great customer service !)

Have a reasonable good focus ...

But still get egg shape stars on some corners...

And it rotates with the CCD (main lens and reducer don't rotate)

This is the one CCD face "up"

Rotate CCD to "left" 90 degree

Rotate CCD to "right" 90 degree

Still need to find out why ... ;-(
