Small dew straps for canon lens

[bloodhound31]

Hi folks,

Can anyone point me in the right direction to purchase a dew strap for my wide lenses for the Canon?

I am using the kit 18-55, but will be eventually upgrading to the Sigma 10-22.

Need something that will keep the dew off both at night.

Baz I use the Kendricks straps.
Take a circumference measurement of the lenses you use and get one that will be close, with a little room to spare.
Then just use the Velcro strap to wrap around the lens.

If I get a chance I'll dig out my strap and let you know what size I use on the 10-22mm.

Prompt and helpful as always Andrew!

Thanks mate, google searching kendricks now.

And I've used DewNot heaters successfully for a camera lens.

Bought mine from Peter Read here:-

If it is oversized a bit, it doesn't matter - it can wrap back over itself, no problem.

But you will need a controller. Build your own with a Jaycar Kit CAT. NO. KC5225.

Thanks Eric. Looks like they are all out of stock...:sadeyes:

Andrew, are you using yours on your DSLR setup?

I regularly take my Canon out in minus temperatures on the tripod with the wide lens.

Anyone got some photo's of their DSLR setups with dew gear, controllers, battery sources? I really need a portable setup that is going to last at least 8 hours.

Baz it's been a while since I've done widefields with my Canon lenses but yes I have used my straps on them when I've imaged.

One night at the pony club I forgot to use the strap, set everything up and set the timer and away I went to chat to the other fellas.
Sure enough the lens dewed over very quickly and the frames were wasted.

I had a look and the 3" Kendrick strap is what I use for most of my lenses, like Eric said a little overlap is fine and will allow you flexibility as to which lens you use.

I don't have any photos of my setup, but I use a Dew Buster controller and my "hot box" to power everything in the field.

I picked the 2" cause it said in stock and it is about the size you want for a camera lens. Email Peter and ask?

When selecting a strap, remember that if it is too short you are in trouble, but if it is too long you can just double wrap it and operate at a lower duty cycle :)

Thanks guys. Looking into it now. Good on you for all that, it really makes life easier when selecting the right gear, to draw from your experience.

Bless ya!

Hi Barry,

I use the Dew Not straps with a Kendrick Controller & have had no problems with them. I bought them from an Ebay Store called Telescope Products Smartastronomy.

The straps are very cheap even with postage added.

Cheers,
