Hi Chris,
I've visually tracked down around 3000 galaxies - mainly using an 8" and a 14.5" telescope. I always used a 2mm exit pupil, as it made the galaxies pop-up easily. But when I used a 4" refractor, on the brightest galaxies, I must say that I was less than impressed with what I saw relative to the other telescopes.
That said, at a really dark site outside Benalla, when Virgo was high in the sky, I swept across it with a pair of 25X100 binoculars - and saw dozens of tiny galaxies on each sweep. And that was with a 4mm exit pupil. Your refractor gathers more light than that pair, and would do a better job at an equally dark site. Virgo is up in the early morning hours now. Perhaps try sweeps across it with eyepieces giving 3mm or 4mm exit pupils. If you find one, increase the power to that of a 2mm exit pupil.
Regards,
Renato
