I purchased a low cost 16 mm extender to reach proper back focus. It was loose and produced a camera tilt. I ordered the ZWO extender and it is solid. No tilt or light in the image train. Just like the one that came with the camera which I had on another rig.

A little bit of adjustment and it is working like a pro with pinpoint stars all the way to the corners. Florostar 110 is 14 years old but still produces some amazing quality pictures that have been made even better with this Flattner. Pic is a single exposure of five minutes.

Helps when balancing my RedCat51.

Exactly what I needed for my telescope. Came with the appropriate screws. Great product!

The Celestron Omni XLT 150 EQ is a great telescope. I'm just getting into astronomy and this telescope checked all the boxes: great build, nice aperture, sturdy tripod, and my favorite part, it's a manual mount, so I learn what's "out there", not having technology do it for me.

Works great. Simple to operate, and I especially like the neck cord to keep it within reach. Thanks to Dave I was directed to exactly what I needed.
