We had a lecturer on board a cruise last year & he set his telescopes up on a couple of the evenings to show everyone the various red, white & blue stars out there (No, he wasn't focused on your flag
He had to readjust every 5 minutes or so, and to be honest, our cheap binoculars were able to give us equally as good images, and a lot easier to pack.
We did have some light polution from the ship, but compared to back home here our part of the UK it was pretty amazing.
