Astronomers can get pretty finicky about cleanliness, especially when it comes to their telescope optics. The reality is that dust is everywhere and it is next to impossible to keep it entirely off a telescope’s optics.
However, you don’t have to allow dust to settle on your optics between observing runs. Astrozap Dust Covers offer a simple, affordable way to solve this problem and are made from a lightweight, breathable black fabric with sewn-in elastic bands to ensure a snug, secure fit.
A sewed in elastic strap allows the dust covers to fit snugly over the open end of a Newtonian telescope, covering the tube and keeping dust out. This helps protect the optics from excessive dust accumulation on the primary and secondary mirrors, which translates into sharper images. There are a number of sizes available for Newtonian scopes.
And models are also available for the increasingly popular 10-, 12-, 14- and 16-inch Ritchey-Chrétien (R-C) telescopes. Match the R-C models with Astrozap’s AZ-1310 to AZ-1320 series shrouds for breathable dust protection of all both critical optical elements and internal surfaces.
For those who own Dobonians, there are sizes from 6-inch to 16-inch telescopes. The Dobsonian dust covers fit both the upper and lower tube assemblies.
The best thing about Astrozap Dust Covers is their ridiculously low price when compared to the important role they play in keeping up a telescope’s performance. Pricing for the dust-cover models ranges from $17 to $21US.
