Lense cleaning?

[gary756]

I was looking a tycho last night and noticed a load of fluff or something in the FOV. On checking my eyepieces and diagonal there is loads of dust. I resisted the urge to give them a good blow and I decided attempting to get a shaving brush in wouldn't be a good plan.

So my question is what are people using, there seems to be loads of brushes and potions on the market. I was considering getting a can of air but know these can leave residue. Does anyone have any recommendations.

Its always a good idea to keep a small bottle of Baader Wonder Fluid in your kit, as well as a rocket blower (as above).

Never breath on lens to clean them. your breath contains a lot of corrosive organics that can damage lens.
