I was more than a bit surprised just how much muck came off my mirror this afternoon! I really must clean it more often :rofl:
I'm sure I gave it a good rinse before Qld astrofest last year, so it goes to show just what a dirt magnet a dobsonian is - Thankfully, the coatings are still pristine after 13 years :)
