I need to mount this on top of an Explore Scientific 127ED Triplet.

Would anyone happen to know the part needed?

Are you using this scope for guiding?  If so, its overkill.

Whichever one of these fits the rings on your main scope: https://www.admacces...s/dovetail-bar/

Thank you Jim but my model is not listed.

Does anyone else have any idea?

Sorry, I linked the wrong page. Those are for SCTs. These are the universal ones: https://www.admacces...l-dovetail-bar/

ADM products are very much worth the price. They are made very well.

From your picture it appears the mounting clamp on your ST will accept either Losmandy "D" or Vixen "V" type bars. The D is larger, heavier and machined. The V can be either machined or cast with the latter being more economical. You probably have a V bar on your mount that your ES127 clamps onto. To be sure try clamping your ST onto that. If it fits then search the usual sites for one sized to your needs.

ScopeStuff  sells hardware to piggyback a scope. I've done it three different ways. I have an ST80 modded with a 2" focuser piggybacked on my 8" dob.

I did the same thing for a while with my ST-80.  I went to scopestuff and bought a mounting rail and tube rings.  I got the rings with the three point screw option to use it as a guide scope but found it was too heavy for my mount setup.  Since then I use it as a second scope with a set of regular rings and a dovetail bar from scopestuff.  It works better this way.

 

Question, which 2" focuser did you get for yours?  I have been thinking of getting one for mine so I can add a flattener to the scope.  Right now the image is way too curved to be of much use, i have to crop so much out of it but the cheaper T-threaded back doesn't fit such devices.
