Binoviewer and Deepsky

I've used my binoviewer on the moon and planets and think it's great. However, the aperture is small (18mm) and won't work well for deepsky objects.

Do folks with larger aperture binoviewers use them on a regular basis for deepsky objects?

I'm debating whether or not to buy the new Deepsky binoviewer (or Televue or AP).

Thanks.

I agree you want a big scope if you are
going to use binoviewer on deepsky. I find
bino does help increase contrast against
sky background. The eye seems better at
pulling out faint stuff when both eyes are
used ... though of course each eye is getting
less light, so there is a trade-off. Few
sights can compare to M13 in a bino with
18" scope... FWIW I've got the Zeiss/AP.
