AstroZap 16吋杜布森望遠鏡防塵罩 - 直徑18吋 - AZ1416

The elastic hem on this dust cover grips the base of my dob tightly, even in a light breeze. It's kept the mirror spotless through two weeks of garage storage. I wish the fabric were a bit thicker, but for the price it's doing the job well.

Finally a cover that actually fits my 16" Dob without being baggy or too tight—the elastic band keeps it snug even on windy nights. It’s a simple thing, but the material feels thick enough to really block dust and moisture when I can’t bring the scope inside.

I’ve been leaving my scope uncovered for months because I hated wrestling with ill-fitting covers, but this one’s elastic hem pulls tight enough that even gusty nights haven’t blown it off. The 18-inch opening gives a little slack for the secondary cage, and it’s wiped clean of dew in the morning.
