I have brushed the dust off of the primary and cleaned the corrector with a no streak cleaner several times, but not very often. It's been cleaned about 4 or 5 times over the last 30 years. I am sure the mirror has lost some of it's reflectivity over the years, but it still performs well. Here is a new image that I took last night under better seeing conditions with Saturn higher in the sky.
