Is this advisable?

Can someone tell me why this is not a good idea? $1.50 dew hood made from flat black poster paper held in place on the 9.25 SCT with a small bungee cable. It’s so easy and cheap, there must be some compelling reason not to do this. Comments?

Thanks,

Al,

I used something like that for a while. It worked pretty well, but moisture would roll down the posterboard onto the corrector plate at times. You could line the inside with felt to help eliminate that, but I think it's a good "poor mans" dew cap.

Al,
Once the paper gets damp with dew, it likely won't hold up nearly as well as you'd like. Why not get some cheap camping foam or crafter's foam as a moisture-proof alternative? A better idea still is to use one of the silver automotive window shields that fit into the windshield of a car. They are cheap, good insulators to keep in heat and moisture resistant.
Best regards,

Don't know for sure, but if the paper gets too wet you might risk ink from the paper getting on your corrector and then you would have to clean it. Worse, if it comes loose it might flop against the corrector. On top of that, in really moist conditions the paper isn't going to hold up long. You'd be better to save your money and wait until you could at least afford one of the plastic models offered by numerous vendors the will attach properly.
