Cleaning the primary, how often do you do it?
I am sure there has been a poll for this before but I am wrestling with a decision to clean my primary. I have a good strategy and intend to set up properly to do it. Potentially no soap and no cloths/cotton balls, just tap water and hand cleaning followed by distilled water to finish up.
What are your thoughts on this? Cleaning the primary mirror seems to create a bit of a division amongst amateur astronomers. I have a film of dust over mine, nothing major, but if I can optimise my scope's performance through a good clean I think it may be worth while, plus, I'm kinda excited by the proposition of getting the primary in my hands and give it a good clean to feel more connected with the scope (i.e. nurturing).
