\subsection{Regular encounters with "real" data and observatory archives}  \label{sec:encounters-with-data}  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 such  as professional astronomers would use. The data are not ``sanitized'', but contain imperfections that the students (and instructors!) must contend with, for example poor seeing, cosmic rays, and inaccurate metadata. 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, in one lab students compare images from ground-based Sloan Digital Sky Survey with images from the \textif{Hubble Space Telescope} (HST), in order to highlight the importance of image resolution and justify the role of expensive space observatories (Fig.\ \ref{fig:hst}). Students pick out details that are visible at HST resolution, which simply melt into the background when viewed from the ground.
