Help With Dew on Canon Clip-In Filters

[russellhq]

I noticed last night I was getting dew forming on the clip-in filter but I'm not sure how to clear it without removing the camera from the scope.

Has this happened to anyone else and any ideas on how to fix it? I was thinking of a dew heater wrapped round the T-Ring but there's not a lot of space there.

what about a blast from a hairdryer down the tube, thats what i do every hour or so just to keep the dew from forming, also a homemade dew shield can be a god send getting an extra hour without dew

Hair drier sounds a good idea.

I was thinking of getting one of these as well as I found it difficult to see the clip filter without removing the camera from the scope:
