Introduction to Observational Astronomy: Night Observing #2 Objective: Continue to learn to use a telescope at night. Procedure: • Take all the equipment you will need outside onto the Green in front of Sharp Lab. This includes: o 6 inch Celestron Schmit ­Cassegrain reflector – Alt ­Az mount (See Figure 1) o Powertank o Case with eyepieces and filters o Diagonal o Make sure that the finders scope is attached. If not, ask your TA about attaching it. • Once outside, make sure that the telescope is plugged into the powertank and turned on. Align the telescope using the remote on the side of the telescope. • Observations: o Ask your TA to identify objects to look at of interest. You should view 3 ­4 objects tonight. If you did not view the moon in the last night lab, and it’s visible tonight, begin with the moon. Move onto any NEW planets that happen to be up. Find one more object to observe and view it using 3 different eyepieces. • Once you have observed an object, make sure to draw it on your post lab report in as much detail as you can. If you view the moon, see if you can label any features. Remember that the telescope flips images left to right. Figure 1: Telescope parts. Figure 2: Tutorial on the NexStar remote. Figure 3: Labeled map of the moon.
