Which counter weight bar is correct?

Apologizes if this has been asked and answered; I searched and could not find anything on this here.

There seems to be conflicting information on the counter weight bar one would need to use with the NYX-101.

In the User Manual it states - "M12 x 1.25mm"
In the FAQ section it states - "M12 x 1.75mm"

Which one is right? I'm assuming it is actually the 1.75mm pitch thread as I can't seem to find anyone that offers or mounts that use a 1.25mm thread pitch at M12.

Can I get some clarification and you might also want to possibly correct whichever one of those is wrong as it's proven to be quite confusing.

I had the same issue here has the OP so I asked Pegasus support. They came right back and stated that the manual had a typo and it is a M12 x 1.75 pitch. The ZWO AM5 bar does work, and I was able to use Celestron AVX counterweights. The plastic M12 cap screw works fine as a toe saver at the end of the bar.

I hope this helps.
