There was fog inside my telescope: Hawke Endurance ED 20-60x85 (1 Viewer)

Is this normal?

It thought the glare was bad from the sun until I happened, by chance, to look at the end of the scope. I took a picture (the fog is on the inside).

It fogged up within 10-15 minutes of being outside. It was a very sunny day and I was facing into the sun. I didn't directly point the telescope at the sun, I kept moving down a hedgerow, with the sun on my face.

I bought the scope secondhand from LCE. It's only the second time I've used it outside and the first time in sunlight.

The fog cleared after 20mins of being in the shade.

Any idea what is wrong with it? I presume this isn't normal. Help!

I had the exact same problem with a Zen Ray ED a few years ago (http://www.birdforum.net/showthread.php?t=219342)
Moisture condensed in the front lens in direct sun..I suspect that the scope was put together and then nitrogen was purged inside the body..but ,what about the air between the two or three elements in the objective?...these a tight closed with seals to avoid moisture to enter,but i suspect air containing hidrogen stays inside the lens cell,and then ,even if the whole body is purged with dry gas,moisture condensation can happen...thats my theory anyway..You should have the scope fixed by the manufacturer...its a shame

It's a bit disheartening to see fog INSIDE the telescope, but it's going back to LCE and will be fixed under warranty (sigh of relief).

Thanks for your reply- I'm not the only one.
