\subsubsection{Hands-on observing experience}  It is a long-standing tradition for AST~208 students to visit the \href{http://www.pa.msu.edu/astro/observ/}{MSU Observatory} for hands-on observing experience, and the redesigned AST~208 continues to uphold this tradition. Students come out to the observatory in their lab groups of 3--4 (at night, outside of scheduled class time) and use the CCD camera to obtain science-ready images with the help of an instructor. Every student is required to visit the observatory at least once throughout the semester. semester, and we aim for more than one visit.  A goal is to increase student access to the Observatory (due through more aggressive scheduling,  to limitations take advantage  of each and every clear night (such nights are limited, due to  East Lansing weather in the spring semester and semester). With  the relatively large class size, size and challenges of transporting students to the Observatory (1.5 miles south of the Biomedical Physical Sciences Building, where class meets),  it proves an ongoing challenge for students to complete multiple labs at the observatory). Observatory.  In support of AST~208, the MSU Observatory underwent a significant upgrade this winter, with assistance from the contractor \href{http://www.astronomical.com/}{Astronomical Consultants \& Equipment}. The observatory is now equipped with a spectrograph, which opens up new avenues for hands-on scientific inquiry with MSU's on-campus facilities. The development of such labs is ongoing, and will be completed and tested next academic year.  In addition, students gain experience with eyepiece observing and telescope manipulation in a newly designed lab making use of the telescopes on the roof of the Biomedical Physical Sciences Building. Each lab group gets access to a telescope; they must calibrate the GPS controls, point the telescope to astronomical objects of interest, and draw communicate  what they see. see graphically.
