I cleaned my primary mirror on Saturday with water/demineralized water etc and it really made a big difference. I used my telescope all of Saturday night and Sunday morning and had a great time but by the time I was finished the primary mirror was soaked in water (from he dew). Even the inside of the OTA was soaked.

I live in a semi-rural area with lots of pollen and stuff in the air so now my primary mirror is all cloudy again. I'm starting to think that washing the mirror is a weakly task - does this sound right?

I have a 12" GSO dob, I don't mind the effort, just want to know if washing the mirror weekly or every few weeks is "bad" in some way?

Thanks for your help Markus.
