Lens hood/dew shield for 20x80's

[RT65CB-SWL]

Hi all,

Does anyone have suggestions for lens hood/dew shield for 20x80 binoculars.

The external diameter per objective cell is 100mm. There is no internal thread, as I did think of using 2x collapsible lens hoods that are used for camera lenses. I cannot find anything larger than 82mm and I doubt they would s-t-r-e-t-c-h to 100mm.

DIY with a camping/exercise mat and Velcro is/was an option, but I do not have access to a sewing machine!

So... [or should that be "Sew..."] ...any other ideas welcome/what do you use?

Hobbycraft do very thin black felt. Works a treat and come in a4 sheets so should be enough to fold around a lens.

To secure I just use black cloth tape. Very strong.

I used a couple of 4"  Black PVC pipe fittings....put a strip of foam weather stripping around one end and they slip over mine just perfectly

I've cut some camping mat out. I haven't stitched them into fixed roll, rather I hold them in place with a pair of plastic ties (the kind you use to tie electric cables together but big ones) which means I can take it all apart and flat-pack it down for storage in a small space.

They do need flocking on the inside surfaces which I must do at some point - it's not a problem for looking at dark things but when looking at bright things you can see reflections from the target bouncing off the inner surfaces of the shields and scattering around the view.

Being an amateur Gardener,I had the idea of using two black plastic flower pots of appropriate size,with the bottoms cut out to fit.

If necessary,the inner surfaces could be flocked,to reduce any reflection.

I'm a great one for theory,but haven't put my idea into practice yet........

I used the stick on velcro tape http://www.ebay.co.uk/itm/Stick-On-Hook-and-Loop-Velcro-Tape-20mm-Wide-Black-and-White-1-to-25-Metres-/151821579177?var=&hash=item23594573a9:m:mh7qFLDtLDLsKEGh6FUqVwg

it works fine, and it's cheap, sticks very well to camping mat.
