Powermate advise needed.

[djpaul]

Looking to get closer lunar Images with my nikon 4300 dslr. 

So looking to buy a powermate.

Would the 4 x 2 inch powermate be an issue.?

Would I be better off with the 2x 2 inch powermate?

Looking to use it on my william optics 73 zenithstar or skywatcher 120 .

I think I would be tempted to try the X4 Powermate,  at a focal length of 900mm it gives a resolution of around 0.22" per pixel.
