Hi George,
You used an old trick. I use a very cheap shampoo to coat the mirror in my
bathroom. It takes much longer before "dew"/watervapor gets grip on the
mirror.<<
Thanks for the bathroom mirror input. I didn't think to use it on my mirror in
the bathroom too? Probably will work there as well?
Huub>> I never tried this on the front lens of my C8. But why shoul'dn't it
work?
Could soap/shampoo do any harm on the coatings ??
>>
I wouldn't recommend putting it on your telescope lens without knowing what it
might do to the coatings. I'm personally willing to sacrifice the coatings off
a relatively inexpensive camera lens for the purpose of capturing meteors. But
this is a conscious decision on my part to solve a problem that I have to
frequently deal with. I think the gain will be greater than any loss that
might occur to the camera lens?
