Coroplast is the name brand of the corrugated plastic sheets. It seems like a great idea for a light shield. After a bit of googling, I found this site which sell all sorts of sheets AND rollable corrugated plastic. The rollable stuff is single sided (enabling it to be rolled), and seems perfect for this purpose. This site sells it by the foot in 24", 48", and 96" tall sizes. You could make a rigid shroud from the bigger sizes. It seems a bit expensive, though, since you need several feet to go around the circumference of bigger telescope. I have never bought from this site, but I might just try some. For the ultimate (albeit expensive) baffle, one would take this stuff and cover it in ScopeStuff flock paper...

Hobby Lobby sells black foam rubber sheets --> http://www.hobbylobb...m-Sheet/p/23080

It may vary by store, but I buy the 1mm thick flat black sheets for 89 cents each. They are as non-reflective as Krylon Ultra Black spray paint, and a lot faster to install than some fabrics. Made a glare shield for my Mogey in about 10 minutes - roll to the desired diameter, glue / tape the seam, and it's done.
