Stargazing Tips for Astronomy Star Parties
Do you know why a no-battery flashlight is ideal for astronomy night sky watching and star parties?
Well, batteryless or no-battery flashlight is not overwhelmingly bright and
glaring, unlike Maglite flashlights. Therefore, no-battery flashlight will not affect your night vision. It is one of the best flashlights for
extended night-time use. Forget about batteries. Just shake and
shine.
Here are some tips on how to use red LED astronomy flashlights to get the most out of your stargazing effort at astronomy star parties.
Use red LED astronomy flashlight for best viewing comfort and stargazing results
To avoid being an outcast in any star party, make sure you
bring a red led astronomy flashlight with you and avoid switching on any white light
after dark.
If you think you will be opening and closing your car door or trunk after
dark, remember to turn off the interior and trunk lights or have them
covered.
Make sure all car headlights are off (or properly covered) when arriving or
departing any astronomy star party observation site after dark.
Tips on how to use the
Red LED astronomy flashlight
Another good stargazing tip is to ensure everyone refrain from flashing any kind of LED flashlight, red or otherwise, at eye level. Keep the beam low and shine towards the ground.
Always bear in mind that the next person might have set her equipment up for long-exposure astrophotography. The smallest amount of light, even from a lighter or a match, will ruin the entire night's effort.
Why is red light preferred over white light at star parties?
This has a lot to do with the way our eyes function. In order to see the
faintest deep sky objects, the surrounding areas should be pitch dark to
allow our pupils to be fully dilated.
After about 30 to 45 minutes in the dark, your pupils will gradually dilate
allowing
more light to enter your eyes so that you may see better in the dark. Besides enabling you to move
effortlessly about in the
dark, you will be able to see faint deep sky
objects. This will help you get the most from your stargazing
activities.
Our retinas are highly sensitive to bright white light and the slightest
amount will trigger the muscles around the pupils to relax in order to shut
out the glare. Smaller pupils means less light entering your retinas
thus interrupting the continuity of your observation.
Once exposed to bright light, you will have to wait another 45 minutes or more to get accustomed to the
darkness again. The brighter the white light, the longer it will take for
your eyes to re-adjust to the dark. Red light, on the other hand, has little
effect on your retinas. Therefore, it is good practice to keep one red
LED astronomy flashlight in your stargazing tool box.
While your eyes are getting accustomed to the darkness, it is a good
time to let your stargazing equipment adjust to the outside temperature.
Although naked-eye observation is a good way to start, eventually, you may want to
progress to a pair of binoculars or a telescope, since they can
help you see fainter deep-sky objects such as galaxies and star clusters.
Tip: This batteryless or no-battery flashlight is ideal for night-sky observation. Unlike Maglite flashlights, it is not blindingly superbright and glaring and therefore will not affect your night vision. It is one of the best flashlights for extended night-time use. Read on and find out how to turn this no-battery flashlight into an astronomer-friendly red flashlight. No batteries needed. Just shake and shine.
How to make a red LED astronomy flashlight
If you do not wish to buy a special red LED flashlight, you can easily turn
any white LED flashlight into an astronomy star party friendly red
flashlight.
For an immediate solution, simply cover the flashlight with several red
plastic sheets or cellophane and tie them securely with a rubber band.
A red LED flashlight is
ideal for checking star charts, changing eye-pieces or setting up your
camera for astrophotography.
Another useful tip is to use any form of light sparingly while you are stargazing. Flash photography is strictly prohibited after dark.
