First off would this be allowed?
I've always thought of buying one but light pollution of the city is one of the reasons I've held off. Seems like the middle of the ocean would be ideal(though minimal outside lights on deck might interfere just the same).
Anyone have good experience with a telescope and could offer their thoughts?
I would think it would be an extremely cheap attraction cruiseships could offer as well. All they would need is to mount it on the side somewhere and maybe man it a few hours daily to help find POI. They could lock it down during the day if the risk of damage was to high.
