Yet another dewshield question

[ronb]

Like many I have made a dewshield for my C11 using an old camping mat.

While a snug fit on the scope I find that the front end tends to droop into an oval section with the vertical section being about 3 or 4 inches smaller than the horizontal.

Has anyone else had this problem and got over it? Does it really matter?

A bit of a bodge, but you could get a wire coat hanger, cut a suitable length of metal from this, form a ring and glue/tape it to the end of the dew shield

Yep have exactly the same problem, though I used a black foam yoga mat so it's probably even more flexible (I'll get my coat...)

You spent £2k on the scope, surely you could stretch £20-30 and buy a commercial dew shield. The Astrozap ones seem to work well. Easy Velcro fastening :-)

I had the same problem. A couple of embroidery hoops sorted it.

Thanks for the ideas guys, I'll give them a try.

A commercial dew shield is just under £50 - OK, not much compared to the price of the scope but makes a DIY one worth a try first.
