I just hadn't seen the E and F Trap stars before even using a Tak FS152. Admittedly that scope was mostly used in a suburban environment.
One time a friend who lived only about 15 minutes away were observing the same night. He was using a TEC140 and me the FS152. He said he could see the E star and I couldn't. I put that down to sharpness of optics.

Put it down to seeing as all scopes mentioned should have optics capable of seeing both E & F. I can see both E and F components in my TV-101 and E component in my TV-60 (still looking for F in it and I believe I have been close), provided seeing is good AND magnification is high enough to give good contrast and clear separation of the component stars. About 180x and over is good. I use 6-3mm and 4-2mm Tele Vue Nagler zooms. Larger aperture telescopes can get affected by seeing more so wait for the right moment during the right atmospherics conditions.
