I have a ten-year-old LX90 that has been in storage for most of that time.
I’ve recently set it up and initial impressions are that the outside of the main lens could probably do with being cleaned.
I seem to recall Meade advising great caution cleaning lenses which have UHTC coatings; even saying not to do it at all.
On the other hand, advice on the Tele Vue web site seems to indicate that cleaning such lenses is not an issue.
What’s the general consensus of opinion out there?
