Reducer 0.66x CDK20 / CDK24

The image circle on my CDK24 is noticeably flatter now, and stars in the corners look like sharp points instead of seagulls. Installation was straightforward, and the 0.66x reduction really speeds up my narrowband exposures.

I paired this with my CDK20 and the drop to about f/4.5 really sped up my narrowband sessions. Installation was straightforward, and the threads matched perfectly with no tilt issues.

I was worried about losing light at the edges of my images, but this reducer sharpened up the stars across the entire field. The 0.66x reduction on my f/6.8 scope makes for noticeably shorter exposures now.
