Actually, I wanted to ask a similar but more general question about
cleaning the scope. When I was collimating the LX200 recently with
the Kendrick laser (which worked great, by the way), I noticed a
cloudy, sticky substance on the glass near the collimation screws.
My guess is that either some pollen got on there, mixed with dew, and
I didn't allow it to dry properly before putting on the lens cap..or it's
some sort of fungus growing there. It's bad enough that it obscures some
of the field of view (a noticable chunk of the concentric rings was
missing during the collimation process, although it didn't prevent me
from collimating).

I read the owner's manual, where it describes cleaning solutions and
techniques. However, their description sounds like it was designed to
remove a few dust particles...not the sticky mess on my scope. Can
anyone suggest a means to clean the optics for something like this?

Subject: [M]: fungal fiends in the tropics

Thanks to all who took up the thread regarding care for the tripod and OTA
when left outside and exposed to heat and humidity. I am convinced that a
pier would be the way to go and easy to keep protected but the expense
remains a limiting factor. The can of WD40, at least, is going no where
near the scope or tripod.

My question now relates to the optics of the LX-200 and the constant
humidity that I am faced with. I work with microscopes by day and the
lenses are pre-treated to inhibit fungal colonisation and growth. I was
wondering if this could be applied to the corrector lens and eyepieces to
their external surfaces. Does anyone have experience with this application
and if it is safe to the optical surface? Since it is used routinely on
microscope optics, I assume it is, but some advice on this would be welcome.

TIA, Alan
