RAS Star Parties
General Etiquette & Happenings
On this page you'll find general guidelines for attending GMARS star parties, but many of these things apply to any star party, whether it's RTMC, Nightfall, an RAS star party at Mt. Laguna, a star party hosted by another club, a star party in another state or even in another country.

Star Parties are typically scheduled for Friday and Saturday nights nearest the date of the new moon. This, of course, is to maximize dark sky time without glow from the moon. Since new moons don't always occur on weekends, there will often be a crescent moon in the early evening or early morning hours.
We encourage you to arrive before dark. This is not always possible, especially at the end of a long working day with SoCal traffic. You are allowed to arrive whenever you can, but if you come after dark, please be sensitive to keeping your vehicle lights off. See the LIGHTS
Many people stay overnight for both nights, some stay for just one night, and others stay for just a few hours and leave. You may arrive and depart as necessary. We only ask that you take proper precautions and considerations for both light intrusion and safety. You are greatly encouraged to seek the assistance of another when leaving—someone walking next to your car with a red flashlight may be able to see obstacles you can't. It's also appreciated if you quietly announce your planned departure so others can shield their eyes or finish an exposure.
Star party activities typically begin in the late afternoon before the sun goes down. We set up our equipment, double check eyepieces and/or cable connections, astrophotographers may start taking flat field images, then break for a meal or snack. At GMARS, that means sitting down to dinner in the kitchen or on the back porch, heading to a restaurant in town, cooking in the RV, or preparing something over the Coleman stove. When the sun goes down, we get down to fun (or business, depending on your outlook). Many will call it a night after a few observations, but there are plenty of nutjobs, I mean, dedicated folks who stay up well past midnight or even until the sun rises.
On Saturday, most will sleep in a bit. The smell of coffee typically fills the telescope field and the house kitchen. Daytime activities are varied and can include hiking the local desert (if it is not summer), reading a book or magazine, processing your images from the previous night, flying a kite, or working on the GMARS clubhouse and surrounding facilites. Another perfectly acceptable daytime activity is napping. Should you come across someone sleeping, please leave him or her undisturbed. Since the family room and kitchen can be somewhat busy during the day, they aren't good places for napping. The bedrooms in either clubhouse (east or west) are great places for catching some Z's.
One of the draws of the RAS star parties at GMARS is the Saturday afternoon potluck, AKA Star-B-Q! The club provides hamburgers and/or hot dogs, buns, and fixings. Attendees provide side dishes, beverages, chips & dips, and desserts. There is no charge for the meal, but donations to the club are certainly welcome and help us pay for the provided amenities.
After that, it's digestion and star party time! See Friday night, add more people, repeat.
On Sunday morning, folks may prepare and eat breakfast or just pack up and head home. The telescope field is usually cleared by about 11:00AM.
Parking is available on-site in designated areas. Click here

Amateur astronomers know that light impedes night vision—one's ability to detect faint objects in the night sky. For this reason, we are careful to use only dim, red flashlights after sun down. The human eye is least sensitive to red light and it therefore impacts night vision the least. All star party attendees are encouraged to use only dim, red flashlights. If you have only a regular white flashlight, the club usually has red film that can be taped over it. Please ask a club member about it. Any emergency trumps our desire for night vision so use white light as needed in urgent situations, and please alert others immediately to any emergency.
It should be noted that even red light can affect one's night vision and observing. Any color of light, if it's bright, aimed directly at one's eyes, or not well-filtered, will destroy a dark-adapted individual's night vision. Flashing lights can be very distracting, and if bright, will affect night vision. Flashing lights may be used to warn aviators of tall structures, but at star parties we're not flying planes. In general, it is best to keep all lights off (even dim lights), unless they are absolutely necessary for walking or reading observing charts and books.
It's not uncommon for new visitors and attendees to shine flashlights at people's faces. Please remind yourself and your young ones to always point the light towards the ground, and use it for walking only. You do not need to have a light on if you're standing still or waiting to view through a telescope. Better yet, control the flashlight for your children.
Automobile lights can be another problem. The time to learn how to control your vehicle's lights is before you come to the star party. It is very difficult to learn how to control the lights in the middle of a dark night at GMARS. Experiment, look in the manual, or talk to the dealer. Most cars have a dial or switch either on the dashboard or on the interior dome lights that allow you to shut off the interior lights even when a door is open. Other drivers may have to locate the switch, fuse, or relay that controls these lights. Some cars have daytime headlights or automatic headlights that are always on. Sometimes these can be shut off by pulling up one or two notches on the parking brake. If they cannot be controlled this way, there may be a convenient override switch or easy-to-use fuse. If not, the driver has a few choices. One could just forego driving at night (preferred). Or, one could tape some opaque (light proof) material over the lights. Another alternative is to park down the road. IF YOU MUST DRIVE WITHOUT LIGHTS and you are unfamiliar with the site, have someone help by walking along to guide you with a red flashlight. We recommend you park at the entrance (with headlights OFF), and walk in with a dim (red) light and ask someone for assistance in parking your vehicle. Although we refrain from using lights after dark, we are also concerned about your safety and the safety of others.
We're not going to tell you not to use your car alarm when at our star parties, but don't use your car alarm (or at least be sure you know how to use it).
Lights should be controlled on the entire site during a star party. Recreational Vehicle windows should be fitted with opaque coverings, and care should be exercised to ensure lights are off when opening vehicle doors. Tents are not light-proof, and a typical flashlight or camp lantern in a tent will ruin night vision for those outside. And for those new to "camping" at a star party, it should be said that it isn't really camping as you may be used to, since campfires are not allowed.
Finally, please ensure your laptop or netbook is prepared for the darkness by using either a full-screen red filter or a laptop tent.
Green Laser Policy
The RAS does not have an official policy concerning the use of green laser pointers. Common sense and courtesy dictate what is acceptable. For sky tours early in the evening, the green laser pointer is certainly a valuable tool. Minimize its use, and no one will likely object to this. As the sky darkens several hours after sunset, many members will be engaged in astrophotography. The use of the laser is not recommennded during this period. If you feel a need to use it, and there is only a small group at the site, we would recommend that you get an "OK" from the group before proceeding.
What cost? All RAS functions are free to all attendees, members or non-members. There may be a donation bucket at some events, but nobody keeps track of who drops anything in the bucket, or if anyone is a member or not. Your camping, food, and other personal expenses are your own. At GMARS, there is no fee for camping. (At some RAS Star Parties away from Landers, you would be expected to pay for your campsite.)
If you enjoyed your night at our star party, or plan on attending one, you may make a donation to the RAS/GMARS Site Development Fund using this form
or by sending your donation directly to:
Riverside Astronomical Society, Inc.
P.O. Box 21264
Riverside, CA 92516-1264
GMARS consists of 10 acres of land, with 2 houses, each on 5 acres. The main house has 2 bathrooms and 1 small bedroom. The other house has 1 bathroom and 1 bedroom. The main house also has a full kitchen. The bedrooms have a few beds in them, which are up for grabs to anyone who wants to sleep on one. They are fisrt-come, first-serve, so it's best to arrive early and place your sleeping bag, blanket, duffle bag or some other belonging on a bed to show that it's reserved. Please bring your own pillow and sleeping bag or other bedding.
The telescope field and parking areas are graded and relatively level. You are welcome to set up tents adjacent to your vehicle and/or telescope. Limited 120V AC power is available on the telescope field for scopes, computers, battery chargers, etc. These electrical outlets are not to be used for hooking up an RV. There are no RV hookups.
Please be aware that the desert sand in the Landers area does not pack well. Care must be taken to drive on graded surfaces and not get stuck in the soft sand. Please keep your vehicle adjacent to the telescope field or other "developed" areas.
Locks & Property Access
You are free to go to GMARS whenever you like, whether it is a weekend, weekday, star party or not. The main house is surrounded by a locked fence, which is unlocked only when a key-holding RAS member is present. There is typically no access to the house and its amenities except during organized star parties and other special events. Electrical power is available at the concrete pads at all times—again, no hooking up your RV to the electrical outlets!
These guidelines should give you a good idea of how our star parties work. The club has not drafted any formal rules concerning what you can and cannot do at an RAS Star Party. Yet, we get along quite well together. But there are some basics we like to keep in mind:
- We do not necessarily encourage playing music or listening to the stereo during the evening star party. If it's something you just have to do at a star party, please check with your immediate neighbors first and keep volume levels extremely low.
- We do not smoke or drink alcohol in or around the telescope field.
- Children should be monitored, and no one should be running on the property, especially at night.
- Members and guests typically wait patiently for their turn to look through a telescope. Attendees with telescopes are expected to allow others to look through their scope (unless they are involved in a specific observing or astrophotography program).
Again, these aren't hard rules, per se. They're just general guidelines provided for those who may not be familiar with how a star party works—or how RASers do their star parties. Star parties should be fun for all. They are social events where the individual is secondary to the group.
Pets are welcome, but must be supervised and under control. Whether or not they should be on the telescope field at night depends on how well they behave but, in most cases, it's probably best if they are kept off the telescope field at night. If someone were to get caught in a dog's leash or step on a dog in the dark, no one will be happy (the dog will probably be least happy). It's also not unheard of for an excitable dog to knock an eyepiece to the ground. That's not fun. Another potential problem with pets on the telescope field at night is the depositing of "land mines." That can ruin a lot of peoples' fun if it gets tracked into an observatory, someone's car, or into the house.
Equipment—Yours & Others
The reason to have a star party is to gather with others and observe or image the night sky. If you have equipment of your own, absolutely bring it! If you want help setting up, just ask—you will find some volunteers. If you do not have your own equipment, feel free to visit with any person on the field and ask what they are doing (one of the more popular pick up lines is, "So... what are you looking at?"). In very rare instances you may run into somebody who is simply working too hard at something to take time to visit with you and have you look through the telescope. This is true for astrophotographers or those engaging in a specialized observing program. These things can take a lot of planning and concentration. However, most people on the field would love to have you look through their scope; just be friendly. You never need equipment of your own to attend a RAS star party.
If you are new to this, be aware that equipment should be handled with the same care you would give any delicate instrument like a fine camera or good crystal. Generally, equipment is not fragile like these items can be, and won't break when touched. However, since the optics magnify so much, a simple touch can disturb the view, and may even move the scope so that you cannot see the object. So, do everything gently.
Remember, it isn't temperature that defines a desert. It's a lack of moisture. Still, desert temperatures in the Landers area can range from 20°F to 120°F depending on the time of year and time of day or night. Temperatures can often vary by 30-40° in a 24-hour period. In other words, plan ahead and prepare for just about anything weather-wise.
When the sun goes down at a winter star party, the temperature can easily fall below freezing in a matter of hours. It is essential to bring plenty of layers of warm clothes. Include long johns, a hat, scarf, parka, gloves, heavy socks, and good shoes for the night. Wool, silk, poly, fleece, down... all good materials to keep in mind for the winter months. Dress warmly from the beginning of the evening. Once the body gets cold, it can be difficult to get your body temperature back to a comfortable level.
Then there's summer. On the warmest of nights it may not drop below 80°F. Sometimes the monsoon weather that blankets parts of Arizona and New Mexico in the summer makes its way west and gives us rain and thunderstorms. Lightning is not unusual around July through September.
Weather & Cancellations
Our experience is that GMARS can have clear weather even as fog or rain clouds are covering the Riverside area, and even as the weather link is reporting clouds in Landers. However, there is no adequate way to notify people of cloud-outs in the desert. Be sure to always check the weather from as many sources as possible before heading out. Here's a good weather resource
We don't cancel star parties due to weather, but you may arrive and find no one else there... which means you probably won't have access to the house and its amenities.
On a star party weekend, you can call the site to get the latest conditions from someone who's there. The GMARS phone number is: (760) 364-1952.
First Timers' Questions
If you have never been to a Star Party before, are visiting for extra credit in your astronomy class, want to know what kind of telescope to buy, are having trouble with your equipment, or whatever—just come on out during a star party and ask away! Just as with any other group, we have some quiet and stick-to-themselves people. However, the vast majority of members are more than willing to share with you whatever they know. They may even provide you with more information than you were ready to accept. The mission of the Riverside Astronomical Society is "Bringing the Joys of Astronomy to the Public." You're more likely to find that joy if you ask for it. First timers especially should attach themselves to somebody and simply spend the evening around them. If you would like such a mentor, just look around. The best candidates will already have a few people standing around looking through their scopes. Simply join in and have fun.
