Lab exercises in AST~208 are created with the goal of yielding an authentic research experience for students. Our redesigned labs are therefore built around real data, accessed from astronomical archives and the \href{http://www.pa.msu.edu/astro/observ/}{MSU Observatory}, just as professional astronomers do. The data are not ``sanitized'', but contain imperfections that the students (and instructors!) must contend with: poor seeing, cosmic rays, inaccurate metadata, etc. Dealing with such often-unpredictable flaws builds student problem-solving skills, while illustrating the everyday challenges of observational astronomy.   In addition, the use of real data from a diversity of telescopes gives students first-hand experience in the pros and cons of different observational designs. And finally, inspecting and analyzing real images gives students intimate knowledge of what the night sky looks like, and how technology can improve our view. For example, as part of in  one lab, lab  students pan around compare images from ground-based Sloan Digital Sky Survey with  images from the Hubble Space Telescope (HST), in order to highlight the importance of image resolution  and justify the role of expensive space observatories. Students  pick outtiny  details that arenot  visible from at HST resolution, which simply melt into  the ground (e.g., that ``star'' in background when viewed from  the Orion Nebula is not just a star, but actually a star with a shadowy protoplanetary disk around it!). ground.
