<![CDATA[Sailin’ Toward the Moon]]>For the past week I was on a cruise ship in the Caribbean, on a “cruise and learn” voyage, serving as one of the guest speakers to a group of astronomy enthusiasts who wanted an immersive vacation learning about the latest in astronomy research and, in my presentations, about the hobby side: choosing a telescope and doing astrophotography. The cruise was organized by Insight Cruises and by Sky and Telescope magazine.

The trip went great, with fabulous weather all along, and a welcome break to an awful winter in the north. However, a cruise ship is not the best place to actually do astrophotography!

This is a shot taken on Friday, March 11, from the upper deck and bow of the ship, the Holland America Line’s “Nieuw Amsterdam,” as we sailed on a northwest course back to Fort Lauderdale from our most southerly port of call in St. Maartens in the eastern Caribbean. The Moon is overexposed at right, and is directly ahead of us, making it look like we were sailing toward the Moon. At left is Orion and Canis Major, tipped over on their sides compared to our northerly view. This was from a latitude of about 20° North.

To keep the stars looking like stars (and not seagulls) and freeze the rolling of the ship, I had to bump the camera up to ISO 6400 and use a 5 second exposure at f/2.8 (wide open) with the 16-35mm lens. Not the best combination of settings, but it’s what it took to capture the “seascape” night scene.
