STUDENT SIGN-UP: Telescope viewing by appointment:
|1||Make an appointment
Select a date you would like to use the telescope. (Try to anticipate clear skies.) Then, at least two days in advance:
|2||Confirm your date.
If there are no conflicts, your chosen date will be put on the observing schedule. Check this site or the observing status sheet outside the lab room.
|Check observing status on your scheduled date after 6 pm. Observing is dependent on the weather. We make a call about whether observing is on or off at 6 pm.|
Show up at the posted site and time. Night observing generally starts 45 minutes to an hour after sunset - see the Status box, above. Dress warm! Daytime observing (e.g. for sunspots) can be arranged also.
General information about the observatory:
|1||Students should schedule telescope time as above ("Telescope viewing by appointment"). Visitors may attend an Open House session (2nd Saturday each month, bar rain) Small groups who are studying astronomy may schedule a time to use the telescope, as above ("Telescope viewing by appointment").|
|2||There is no fee. We only ask that you abide by dome safety rules, and help us accommodate everyone.|
|3||The observatory is not appropriate for young children or infants. Please do not bring them. Children under 12 should be accompanied by their parents. Please, no running or other horseplay.|
|4||There is no seating, bathrooms, refreshments or heating in the observatory. It is a working scientific facility, intended to enable students to do real-world work in astronomy. If you are a visitor, think of it as a science laboratory.|
|5||The dome is 15 feet in diameter. This is spacious for our purposes, but small compared to an observatory like Fernbank. We need to limit the number of people inside to 12.|
1. Please pay attention to the Dome Operator at all times. Be aware that the dome is a machine, not a building.
2. Entry is through the door when the Dome is in the home position only.
3. Only the Dome Operator may open the door. This is important!
4. No running or other horseplay.
5. When inside the dome, keep away from the wall (1 foot), and the telescope when it is slewing. Both the dome and the telescope rotate as we look at different regions of the sky. Both have powerful motors. Do not lean against the wall. Do not turn your back on the telescope. Pay attention to what is going on, as you are likely to get disoriented as the dome and telescope rotate. This means you should limit any cell-phone conversations to the bare necessities (say, 15 seconds). Sorry, but if you need to chat, you should not be inside the dome.
6. Please do not pick up or disturb any items or equipment unless invited to do so by the Dome Operator.
7. Please park in the parking lots.
|7.||The viewing pad around the dome is an excellent site for viewing the skies. Your eyes are the best astronomical instrument in the world. The solar system, our galaxy, the universe are all there to see if you know how to look. A telescope shows the details, but only your eyes can take in the Big Picture.|
|8.||Telescope piers. We have four piers on the pad for mounting telescopes. These piers are solidly mounted for stability and are a much better option than a tripod for setting up a telescope. Visitors are welcome to make use of these. Contact us about fitting your scope to a pier. (We can get mounting plates for specific models of telescope mounts.)|
|9.||Binoculars are another option for the viewing pad. Ask if you would like to use a pair, or bring your own.|
