James, et.al.,
Have you achieved any preliminary results in your coating test?

P.S. There are a number of SPAM posts you need to remove from this forum.
I'm rather interested in any results as well.
And yeah, it'd be nice if the spam went away.

There is a lot of different gadgets that astronomers or star gazers like to
incorporate into their night time viewing activities to enhance the experience.
From tools like powerful cameras, high tech telescopes, and bright laser
pointers you can really have quite an impressive set up even for a personal
collection. It is a great hobby for kids and adults alike, and can be a great
way to incorporate learning and fun.
But what are the best laser pointers that you can buy for astronomy use and what
types of things should you look for when you are searching online for a sale.
Well, first of all you want to have some idea of what kind of a price range you
are working with. This will be one of the largest factors in determine whether
or not you go with a cheap laser over another.
Next you want to consider the color of the laser beam that would best suit you,
green lasers are the brightest and are most commonly used for astronomy but
lasers are available in a variety of colors. Red, blue, yellow, purple, of
course green, and even infrared are all available in the convenient hand held
portable sizes laser pointers provide. Most likely you'll find green is the most
suitable for night time use but really any of the lasers will look great at
night and can really add to your star gazing experience.
Keep safety in mind as the quality of every laser pointer can vary greatly as
most shoddy designs don't have IR filters that block the dangerous light from
being emitted. But all in all lasers are fun and can really make astronomy all
the more exciting.
Do a little bit of research into any laser brand or specific model that you're
looking at, see if you can catch a few videos on YouTube or find some tech blogs
reviewing the laser. This way you can get a good idea about what you can expect
from any individual laser. You want to do this because something too cheap can
burn out quickly and not even be worth the cardboard box it was shipped in, so
be careful and do a few minutes of browsing before you jump into any laser tool.
All in all though, any laser will enhance your astronomy experience so enjoy.
