Dew straps

[bomberbaz]

Looking for other peoples solutions for dew control for their imaging rigs and suggestions for mine.

First here are my scopes that need protecting, the rvo horizen 60ed (built on shield about same length as aperture) and astro essentials 30mm mini guide. Similar dew sheild to horizen. 

First question is will a simple extention to existing dew shield suffice on these modest apertures. I ask because that what I use for visual and I have never experienced any moisture issues when doing so.

If not, I think I would be looking for a simple USB powered solution, much easier transportation and less clunky. I have numerous power banks too. 

I have looked on FLO but sadly they are without USB type tapes. 

TIA everyone

Steve.

Coowoo straps on Amazon worked just fine for me until I moved to a powerbox and needed different adapter type.

 

In fact let me check I have the name right as can't find them lol

Yep, here you go, have  a search for different sizes...

Hi Steve 

With my 72ed I use a dew strap and one on my 30mm guidescope. I've not really noticed if I had dew issues prior to the dew strap on the 72ed. So I thought I'd go for dew straps just incase. I've got these on the bay of e here and 3 heat settings.

I've just seen they are out of stock on bay of e but they are here on amazon.

And I used to power them via a talentcell battery with a y splitter cable but now use this mains powered USB Hub.

Put a sock on it!  Cutting a hole in the end of a sock and slipping it over your telescope keeps the tube, cell and dewshield from getting too cold. 🧦

I have two of the coowoo USB dew straps (from Amazon) and they have worked well with my guide scope and 102mm refractor. I couldn't get these to work with the ASI Air Pro but just used a separate plug with 2 USB ports in.

Good idea Mike, I actually have a sheet of kits playfoam, very malleable. I will make a foam sock as it were out of it as a permanent sock 😄
