[g__day (Matthew)]

I have been away from visual astronomy for a while now, but with the purchase of some APOs recently I have delighted to return to some visual enjoyment at the scope. I'd forgotten a problem that use to annoy me - my own breathe I supposed fogging up the eye piece whilst I am observing.

Whilst I was observing Saturn - I noticed a light fog form on the centre of the eyepiece after I had placed my eye near it and commenced viewing for a few seconds. If I moved away from the eye piece the fog would evapourate after 10 - 20 seconds. So I imagine this is water vapour coming from my breathe, traveling around my face and body and some condensing on the eyepiece lens.

I could wear a scarf - to try and trap my breathe - but does anyone else have this challenge and how do they best solve it?

Many thanks,

Matthew
