That's a great idea-gorgeous photo!

This system seems to be working fine but the wireless shutter release uses CR2 Lithium Ion batteries, which are $6.98 each and at 25 degF they only last about 3 hours, however I found a source for two rechargeable batteries and a charger for under $20 on Ebay.

I was concerned that the camera might not work well at that temp but it is doing fine, of course you have to leave the power on, which reduces battery life to 4hours, but that is not a problem because the Pentax *ist DL uses four standard AA batteries and I already have 24 rechargable AA's.

That really is a great idea. I have tried using my remote shutter attachment, but that only gives me about three feet. A wireless shutter release is something I need to look into. Thanks for posting the picture and the idea.

I say it is working! That is a spectacular shot of the Downy.

Check out Ebay.I found my wireless shutter release for under $20 with free shipping.

Also, if the wireless shutter release for your camera uses CR2 batteries I would strongly suggest you get a couple rechargeable batteries because the batteries are $7 each and only last about 3 to 4 hours in the cold. A pair of rechargeable batteries and charger are under $20 on Ebay.
