Its not been very good weather anywhere lately for astronomy gear.

Hi Paul
Ouch re the WO fungus, that is most unwelcome news indeed and I feel your pain!
I relocated all my optical stuff into the spare room and use a dehumidifier throughout our humid summer months to keep the room at around 60-65% which if I use my camera and astronomy gear on a regular basis, seems to keep the fungus at bay.
I recently started keeping my EM200 in the room as I noticed fungus appearing on the reticule of the Polar Alignment Scope.
The water container in the dehumidifier has a capacity of 12 litres and during the worst days of the season, it can almost fill up in a couple of days.
Good luck – it is a battle worth fighting given the cost of our gear.
Cheers
Dennis
