One of the problems I had with the construction paper was sagging -- that might happen with plastic too, but I don't know.

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. ----- Original Message ----- From: "Joe Bauman" <josephmbauman@yahoo.com> To: "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Sent: Wednesday, November 9, 2011 12:47:57 PM Subject: Re: [Utah-astronomy] Dew/Frost prevention 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.

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. _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php
