Powermate/ZWO adapter

I recently received my Powermate 2.5x to use with my Lunt 60mm and ZWO174MM. Immediately noticing severe ghost image. A bit of Cloudy Nights reading shows this is a known spacing symptom and seems replacing the eyepiece (camera) holder on the Powermate with a Televue T ring adapter PTR1250 and then another adapter to mate the Powermate to the ZWO resolves. Cost is $85 plus whatever part I need for the ZWO. Can anyone advise if there is another generic way to achieve same outcome. Thanks for any input.

Peter,
Not sure there's a generic adaptor....
I use the x2.5 PM with the T thread adaptor, and a ZWO T2 tilter (to suppress Newton Rings) on my SM60 set-up.
The ZWO camera has a front T thread so it should fit directly to the PM adaptor.
