Observing at night

From Slackerpedia Galactica

If you're going to be into astronomy, there's going to be one main time of the day you'll be doing it - at night. When the sun sets (or to be astronomically correct, we revolve away from the Sun), all the stars (which were there and technically visible during the day) will become visible. Observing the stars, while not as challenging as rocket science or eating your VCR, still requires some preparation beforehand.

Light Pollution

Scourge of the astronomer and creator of the Faint Fuzzy, pollution from mostly artificial light sources can limit the amount of stellar objects you can see as well as their brightness. And despite the most expensive telescope or pair of binoculars you can buy, they cannot cancel out thousands of city lights. This is why even professional observatories such as Arecibo Observatory are miles away from civilization. Beyond mounting an illegal luddite-like attack on your local power planet, there are several other steps you may take.

1. Find a local astronomy club or chapter of an amateur astronomer society. They often have access to great spots no one knows about, and you'll be observing the stars with other people who share your hobby and passion.
2. If you're more comfortable with observing by yourself, use your rooftop or that of a friend which will limit some of the light pollution from your immediate neighborhood. A balcony can also do the same job.
3. Plan an astrophotography outing with friends who like astronomy to a suitable spot away from the hustle and bustle for some really great shots.

Safety

1. Check weather forecasts to ensure that there will be little wind or precipitation.
2. Don't observe where it's illegal. You certainly don't want to be attacked with a telescope.
3. Protect your equipment, especially if you're going a long distance. Waterproofing, cases, and straps are a must.

Preparation

Try to bring the following items with you.

1. Telescope (Duh)
2. Binoculars or spotting scope
3. Notebook (for recording and sketching)
4. Star Atlas (Your little cheatsheet)
5. Flashlight with front covered by red or blue film
6. Lens cleaning kit (Cloth and any non-abrasive liquid)
7. Cellular phone (for safety reasons)
8. Psychotropic drugs (If you want to really enjoy the view)
