Red and White Light Rules
Dark adaption can up to 30 minutes to become fully effective once your eyes are exposed to bright lights - so, we are going to make the rules very simple:
Red light affects the eye's dark adaption the least - however, even bright red light can impact this - so..
Tent / Caravan Lights
It is easy to forget that interior tent lights can actually make your tent glow and ruin the darkness for other people.
Although we are very pleased to see families attend the star party, please ask them to understand the reasons for keeping lights down. Again, dim red lights should be used.
Van owners - please make sure you turn out your outside lights, and close your curtains/blinds
Many cars will flash their lights when locked and unlocked. Where possible, please either disable your car lights or tape them over with red gel or black bin bags.
If you forget and you absolutely must open the car when it's dark, please alert people around you, and give them a few seconds to shield their eyes.
Call out something like "lights on in 5..4..3..2..1" - yes, you will feel a wally first time, but people will thank you for the warning!
If you are an astro-imager, please be aware of others around you = they may be observers only and light from your computer screen may well interfere with their ability to observe the night sky. Your screen must be covered with a red filter and have the brightness turned down as much as possible.
Ideally, the screen should be shrouded so that extraneous light does not leak the surrounding area.
In the past, this has been the biggest single complaint regarding white lights - we will police this very firmly!
Laser pointers are not permitted. We may organise a short public tour of the night sky, in which case, the Astronomer giving the tour may use one - this does not mean they may be used by anyone else.
What if I forget ?
Don't panic! The Mod team are here to help - find one of them, and they will be pleased to assist in anyway they can
