Interesting. I seem to be out of whack with a lot of people here. While I find a 3mm exit pupil indeed best for faint open clusters (and there are areas of the sky where they abound), time after time I've found the 2mm exit pupil to be superior on galaxies and very faint nebula. I just can't see them as easily at either 2.5mm or 1.5mm exit pupils at a dark site.
