Stargazing on a Cruise: What to Expect

Firsthand Experience

I recently took a cruise to Alaska and was excited to do some stargazing. However, I was quickly disappointed when I realized how light-polluted the ship was. The outside lights were so bright that it was difficult to see anything but the brightest stars.

I spoke to other passengers who had similar experiences. One woman told me that she had been on a cruise to the Baltic around the summer solstice and had been hoping to see the midnight sun. However, the ship's lights were so bright that she couldn't see anything at all.

What Causes Light Pollution on Cruise Ships?

There are a number of factors that contribute to light pollution on cruise ships. One is the sheer size of the ships. Cruise ships are often very large, with thousands of passengers and crew members. This means that there are a lot of lights needed to illuminate the ship, both inside and out.

Another factor is the type of lighting used on cruise ships. Many cruise ships use LED lights, which are very bright and energy-efficient. However, LED lights also emit a lot of blue light, which can be particularly disruptive to stargazing.

Tips for Stargazing on a Cruise

If you're hoping to do some stargazing on your next cruise, there are a few things you can do to improve your chances of success.

• Choose a cruise line that has a good reputation for stargazing. Some cruise lines offer special stargazing cruises or have designated stargazing areas on their ships.
• Book a cabin on a lower deck. The higher up you are on the ship, the more light pollution you'll experience.
• Bring a pair of binoculars or a telescope. This will help you to see the stars more clearly.
• Be patient. It may take some time for your eyes to adjust to the darkness. Once they do, you'll be able to see more stars.
