Hi
I want to connect my Skywatcher focuser to my coma corrector (which has a 2" base).
Unfortunately, my focuser only has an m54 to 1.25" adapter. Any suggestions on how to fit a 2 Inch eyepiece?
There are adapters available overseas: https://www.firstlightoptics.com/adapters/astro-essentials-2-inch-compression-ring-adapter-for-sky-watcher-newtonians-and-72ed-refractor-m54.html
but I would like a local solution.
Calls to aussie shops (skywatcher, BinTel, Testar etc...) have not be successful - any ideas?
cheers
Mark

I think the m54 is the same as the takahashi wide t mount I think and probably others. So I am sure there would be m54 adapters out there.

I stand corrected. The takahashi M54 is 0.75 pitch.
I think the skywatcher focuser is M54 1.0 pitch
Arrrgh.

Ask Joshua Bunn to make an adapter.
