Powermates are the highly-evolved answer to the Barlow lens design from Tele Vue.
While barlow lenses increase the eye relief of the eyepiece in use, they also reposition the exit pupil of long focal length eyepieces far from the designer's intended position. This can cause vignetting and image degradation.
Using four elements, the Powermates leave the exit pupil where it was intended to be, restoring the full viewing aperture and optical quality of long focal length eyepieces. Have the best of both worlds; the long eye relief of the longer focal length eyepieces, but with higher magnification!
Nearly parfocal with 2.00" diagonals, the 2.00" Powermates are threaded to accept 48mm filters and their performance is exemplary with every 1.25" & 2.00" eyepiece in the Tele Vue line.
Directly accepts all 2" eyepiece
Threaded for 48mm filters
Works well with diagonals, unlike many normal Barlow lenses
Accepts optional PTR-4201 SLR camera adapter (imaging w/o eyepiece)

How does this work with the Meade LX 600 12”? Would it be too much? I would like to do planetary photography with either a Nikon D750 or a Nikon Z6. Thanks

This would work with the LX600,but might be very dark/distorted. You can definitely try it with the Scope. The View just might be a little grainy due to the high magnification.

I have a 2x Powermate and mount it directly to the 90 degree Televue Everbrite dielectric on my TV-85 for viewing with both the eyepieces and attaching my DSLR via the Powermate adapter with T-ring. Is this how the 4x mounts as well?

If I undestand your question correctly, I say YES. I have used my 4x Powermate on my Meade 7 LX200 Mak-Cass with a 2 Diagonal. I dont really need that much magnification on my scope when viewing VISUALLY, why I bought it was for shooting Prime Focus using my Canon T3i DSLR. For this it performed flawlessly. Im pretty sure you are aware these Powermates are a step up from the lowly Barlow and its quite noticable once you've used both and compared the differences ! Just be sure you have the 2 adapter if you are using this 2 Powermate. Aside from that, keep looking up ! :-)

Does 4X powermate, 2 , fits in to SCT rear cell adopter(2 ) or directly in to SCT rear cell(I have 8 SCT). In other words how do I hook up this 2 powermate to rear of 8 SCT.Second Question: I have a cannon DSLR with T ring and 2 adopter. Does this works with this?.

This piece has no thread, so you have to have an adapter for your SCT rear cell (same as you would require for either 2'' diagonal or a 2'' eyepiece). If you have one, you can hook it up just as you could hook up any 2'' eyepiece or a diagonal. Powermate will also accept a DSLR with a 2'' male adapter, however, there is a special ring from TeleVue that can replace the original barrel, so that you screw your DSLR closer to an optical element.
