James, Thanks for the link to http://stargazerslou...den-dew-shield/

I like it too! I wonder what the weight is, being made out of veneered ply? Certainly for my dobs, weight is very important - every kg at top has to be counter-balanced with 4 or 5kg at bottom (due to differences in distance from fulcrum) - I have a large collection of various magnetic weights!! Actually on that point, I have found the magnetic strips you buy from Wilkos to put tools on wall in garage make great magnetic weights - sold in packs of three of different sizes - just like the scales in the kitchen can choose combinations to balance most things. Only problem is I now need 2 packs, what with Telrad, 2 inch Explore Scientific eyepeices (weigh a ton) and dew shield on top!

Hi Baggy (or Wrinkle?)

I think you are probably right! Keep it simple, light and cheap.

I'm finding similar problems with my own dob as I've moved to the more expensive end of the market with eyepieces. I am going to have to start thinking about counterweights soon.

I am already up to 10kg+ counter weights some times on my Dob!

A pic of my one on the 6SE.

I found my ED80 hardly ever dewed up, but that could well change when I am back in the UK.

Everyone knows you should use a yoga mat not a camping mat. Helps you be more at one with the universe.

Seriously though, they sell foam mats in black if you're buying from new. They're still a bit on the shiny side generally though and have had reflection problems with them in the past so probably worth getting some flocking material at the same time.

I've made one using a camping mat for my 250P last week, I also did the same for my 200P & stuck some velcro on both.

Very good - do you use Velcro?

Andy

I used velcro tabs (3M) that are used for picture hanging.
