This is the twenty-inch Newtonian reflector at the Centre for Observational Astronomy in the Algarve, where I have just spent five nights

And this is roughly what you get if you point it into the middle of the Virgo galaxy cluster, attach my nice camera, leave the shutter open for 90 seconds at ISO1600, and tidy up a bit in Photoshop afterwards.

galaxies

I think there are six and a half galaxies visible here; M84 and M86 are the big ellipticals top and bottom respectively, NGC4387 is the little one in the middle, NGC4388 is the interestingly-shaped one on the right, NGC4402 is the dim fuzzy one on the bottom left, IC3303 is the teeny faint one you get to if you start at M86, go to 4387 and keep going, NGC4413 is the half-cut-off one right at the bottom on the right. I'm not at all sure what the name of the tiny companion galaxy about a centimetre at clock-7:30 from M86 is.
