Hi Peter
The bed roll is a good idea, but if you want a shield to match your scope check with Mick Pinner first as it won't cost anything like a Meade.
Another option for Dew Straps is to try John Marstiller at
www.dew-not.com as they don't draw as much power as other brands. We use them on our eyepieces as well, both 2" and 1.25". Living among mountains we get pretty heavy dew and we have stayed out as late as 4am.
