NCO was built in 1984, and has gone through 2 renovations since. Some of these pictures were taken long ago with digital cameras that were very low resolution. However, it gives an idea of the changes over time, and the few scopes that have been in the building. Not all are represented, since some scopes never had pictures taken. We recently renovated it again this year (2012), and there is now a 10" f/8 RC imaging system (2017)
