I was thinking of getting a pair of 15mm superviews to use with my Binotron-27 on my ES 5" apo but which one is better?  Thanks for the help.

They are literally the same eyepiece.

I thought so. Are they good at F7.5?

Not "good" at F/7.5 but maybe good enough if you are mainly using the eyepiece as a finder.

If you enjoy wide, low power sweeps of the sky there are better choices IMO.

Neither of them. Save for something better.

I had blackouts using both the 15mm and 20mm Superviews in my F4 reflector.  I didn't like the critical eye position with these.  The 15mm was slightly better than the 20mm.
