I really like(d) my Celestron 8" dew shield, it held up really well; I lost one that came with my scope when I bought it in 2008; it was 10+ years old but I great condition. The one I bought for my 8" as a replace was the same flexible one from Celestron. They hold up well as are nice and lightweight.
My CPC 1100 came with one already (astro zap aluminum version with the not lches and an opening for Hyperstar cables). It's a bit easier to put verses the Celestron flexible one with Velcro. But is that worth the $135 price difference, no.
I'm in vacation with family sans any astronomy related equipment :-(. However when I get back in town, I snap some pictures of the case with the scope in it.
thanks Mike. I appreciate it.
