    Default View On or Close to the Beach



    My closest dark site (Bortle 2?) is on or close to the beach. This is out of town. Quiet beach of a small town (not commercialized). No lights except what people bring with them

    Question is:
    What effect will the salt air/ wind have on my scopes OTA and lenses? There is a constant west wind that blows. Only the strength of the wind differs (mild breeze to 42 km/h)

    42 km/h you would have to stake things down to keep from being blown away!

    The wind will shake the ota some but doing visual work its not that big of a deal.

    Salt spray on the other hand is an issue. Salt spray built up on the lens / mirror etc. will pull moisture out of the air and you will soon have a mess on your hands. Not to mention the problems with corrosion eventually.

    I would say on calm nights you would be fine. On breezy nights I might think twice.

    If you can get back away from the beach, even just a few dozen meters or so will help. Besides all that sand will be pesky too.

    Hello Slabs,

    the effect of the salt aerosol and of the fine sand would be damaging.

    Did you ever see the movie Alien Nation? When the aliens come into contact with salt water they would dissolve. Okay, its not that bad, in the short term, but your optics will not fare well in the longer term. That's not to mention the sand. I spent many summers with beach houses on the Outer Banks and the most I would risk is second tier binoculars.

    I had a dark sky trip to a beach location last year - brought my Z10. I was about 200 feet from the water and staying at a beach house. Conditions were not windy nor was there much sand in the air and very little spray, in any.

    I really enjoyed the dark skies and my scope made it through with no ill effects. So, I wouldn't make it a regular practice but on occasion you should be fine. Another great thing about the beach is the unobstructed horizon, allowing you to see the stars and Milky Way appearing to dissolve right into the water on the horizon - pretty cool.

    Was not planning to view on breezy nights. That's what the Bono's are for.

    Yes the horizon is what made me think about it.

    There is no true advantage of viewing from a beach. The actual advantage comes from viewing over a body of water at night. Obviously light pollution is not there, and the air over a body of water, even the ocean is more settled. As others have suggested get away from the actual beach, while still being able to take advantage of the geography of the location

    If it was only for a few nights of gazing I'd say you'd be fine as long as there is no high winds blowing sand around. I would not make it a habit using fine optical and mechanical fear in said conditions. I'd also clean everything after each session especially any salt spray on the optics.
