Lens Cleaning
« on: 14:18:07, 27 September, 2013 »
Ok . . . I've got the kit, taken the pictures and now has come the time where I need to do a little bit of maintenance . . . .

What is the best product to use in order to clean coated optics?

I haven't touched it as of yet and now its starting to collect a few dried dew marks on the front and don't want to just go in there with a lens cloth and wipe away in case i damage the coatings.

Thanks

usual advice for cleaning optics is : Don't.

But more practically - I do mine once a year at most.

Mike, unless you're talking mirrors, lens coatings are usually pretty tough.  So, aside from recommending a lint free soft cloth, most optics cleaners should be safe.  Your local drugstore (or is it call chemists over there?) should have a selection of optics cleaners for eye glasses and such.  I use a generic brand... for what it's worth the majority of optics cleaners use some combination of alcohol and distilled water.  Nothing really magical about it.

I also use optical wonder, my small bottle has lasted 3 or so years and is only half empty, it comes with a very good quality microfibre cloth, it definitely should be in your kit

Thanks for the advice guys, I have got some 'wonder' from Modern on order, but following on from Tom's comment, is cleaning to be kept to a 'when absolutely necessary' scenario?

I know prevention is always better than the cure, so with the dew shield on and 'when' i get the heater strip and controller, that should bring the requirement of cleaning the optics down to a minimum should it not?

Once a year is also about how often I clean my optics too, keep them dew free and capped when not in use and that should be more than enough, my eyepieces on the other hand tend to get cleaned more often as I do forget to put them away sometimes, but regular cleaning certainly hasn't affected them
