Most discussions I read about concerning telescope optics, relate to how 'Very Cold' temps. might affect lenses/eyepieces/mirrors etc. But what about High Temps? Are most binoculars/scopes/eyepieces/computerized mounts protected to some degree of excessive ambient heat? At what temps would these be in danger of being damaged? Coatings/cements/electronics/expansion of glass?? The Government Run Apts. where I live are planning 'Heat Treatments' on their units. Should I Run? (Can't Anyway). They are talking reaching ambient temps of 140-160* for 2 hrs., and don't want anything removed. These people are not the kind that are much concerned about 'individual rights' or "personal concerns" of those that are their clients, - they pretty much play, - "Our game, - Our ball", Don't like it?, - Get off the Field.

I'd imagine your glass and aluminum will be fine.  I'd try to figure out a way to get your electronics out, though.

Sounds like they're trying to get rid of bugs.  ICK.  But you've gotta do what you've gotta do...

 

I would not leave my OTA exposed to that.  It won't be a slow buildup to that temp, it will be with heaters at 100%.  Doesn't sound good to me.

The bedbugs aren’t on you optics.  Put them in your car.

Cars get hot too, unless parked in a sheltered, shaded place.
