    Default Observing from a cruiseship



    Yesterday I saw the Italian cruiser "Costa Luminosa", a huge floating building in the harbor of Auckland and spoke some Germans who made a world cruise with it.

    Well, I am not interested in cruises as it calls on ports only for a few hours and the remainder is 'entertainment' on board which costs $10000+ a pax all inclusive.

    But nevertheless I am interested whether there are people interested in stargazing on a ship. The sky must be very dark on sea, but local ship lights may spoil it, and observing might be limited to handheld devices such as binoculars only as telescopes do not render a steady image as the ship always moves a little, even on calm seas.

    Some experiences ?

    Never tried it but an interesting idea. If you can get away from the bright lights the milky way is visible from horizon to horizon. I've heard this experience from my father (ex-Navy man) who attests that the number of stars one could see on the open sea is virtually uncountable.

    I've always wondered how steady cruise ships would be. The larger the boat, the steadier, especially with calmer waters, but when you get to cruise ship size, could you observe at least with a fairly low magnification?

    One of the guys in our astronomy club gives presentations on astronomy on cruise ships. He's now done this several times. He and his wife get a free cruise and in exchange he gives a few (don't remember how many; 4? 6?) presentations. (He's given his presentations to our club, and they're good!) I think maybe he leads some outdoor observing sessions for them too.

    The best wide field views of the night sky are obtained with your "Mark 1 Eyeballs". The night views of the milky way and shooting stars at sea are exhilarating.

    I went on a Carnival Cruise to Mexico and took my Canon IS binocs to see what I could see. Unfortunately, the lights from the ship itself pretty much ruined the views, though it was better than what I could see from my sub-urban back yard.

    This is what I sought. It is a floating Christmas tree and I don't think you will be able to convince the captain to turn them off.

    Cruise ships today definitely stay lit up and you can't get forward of the bridge like on the old ships. That was always kept dark when at sea. Princess cruises have dedicated stargazing cruises and I have heard of some other cruise lines doing some stargazing activities. All stuff that needs to be checked out well before booking.

    skysurfer,
    I took a cruise from Vancouver, BC to Los Angeles a couple years ago. There are only a couple spots on the ship that are worthy of giving the stars a try. The top-most deck was not being used late at night, so there were no cruisers up there, however there were lights on. I found a corner of the deck where the lights were less obtrusive, and I had a hood that covered my face. So, the hood, a lounge chair, and 15 X 70 binoculars provided as good a view as I was going to get. With the lights covered (hood) there were gobs of stars lit up and the Milky Way was easily visible. At that time the ship was between Victoria and Port Townsend. When we were in the ocean cruising south along Washington, Oregon, and California the skies were darker, but there were low-lying clouds most of the way.
    There are cruises that offer stargazing, Star Ships: New Sciences Cruises Offer Pristine Cosmic Views. Don't know about their success rate.

    I took a small 100 passenger ship across the Atlantic crossing near the equator in 2013. It was an eclipse intercept cruise, all passengers were at least eclipse chasers and many were astronomers. There were lights off stargazing activities. Skies are dark but transparency is poor. I get better skies here driving an hour out of town.

    With stabilizers on this smaller ship rolled by +/- a couple of degrees in each direction from level.

    Don't take the cruise for stargazing but do try some if you're taking the cruise anyway. Maybe bring a cardboard lens hood to shield your naked eyes from the lights.

    Image stabilized binoculars probably won't work to steady the roll of the ship. The stabilizers work at frequencies around 50Hz to counteract muscle tremors. The ship rolls over many seconds. Stabilizers aren't designed to work at those much lower frequencies.

    cheers
