This uses the same type of foam that Mat is talking about. It works very well. Clear skies, Dale.

Thanks, Dale. Do you have an email address for Mr. Seargent? -- Best wishes, Joe

I made a homemade dew cap for my 10" LX-200 from a thin blue exercise/camping mat based on some directions from Jim Seargeant (who now lives in New Mexico). I used contact cement and a smaller piece of the mat (on the outside) to glue the seam together. I flocked the inside of the dew cap earlier this year. It has worked very well for over five years now.
I made a few cutouts for the dovetail bar I have on the top of the scope and a smaller cutout for a 2-D weight bar that I have on the bottom of the OTA.
Jim's scope was a 12" LX-200 just like yours Joe.
Clear skies, Dale.

What about a sheet a plastic? You may be able to role that into a tube, considering the diameter of your scope. Of cours, that would have be a pretty long sheet of plastic.

Mine would have to be two feet long, and I would need to make sure it didn't stick up over the guidescope or throw the telescope off balance. Once I tried with a homemade one, stiff construction paper, but I had so much trouble keeping it taped together that it wasn't worthwhile. But I had put it together in the dark while observing. I bet if I made one at home it would work better. Thanks, Joe

You know, Chuck, commercial is probably the best route for me -- when I can scrape together the dough. I'll check out OPT. Thanks, Joe
Do you use a dewcap? Per Patrick's post, one about two tube diameters long can go a long way to keeping your corrector plate clear.
