Several members of RAC (and a couple from CHAOS) joined Jim Pressley and Phyllis Lang at the NCSU Crafts Center Saturday for an informal eyepice cleaning clinic. Supplies and refreshments were provided for attendees who brought an eyepiece or two for cleaning.

Jim began by discussing the importance of clean eyepieces for visual observing. He described the materials needed for cleaning and his method. Next we discussed some of the pitfalls of cleaning eyepieces like keeping fluids away from a lens edge where it can leak around the edge and underneath the lens. Following some Q&A, attendees began cleaning and assessing their eyepieces.
Hopefully everyone left with a new appreciation of how to carefully clean an eyepiece, and tell when it is really clean.
