Dust cover for 8 inch Dobson telescopes | Astrozap

A Dobson has an open tube at the front, and this makes dust easily get onto the viewfinder and main mirror. With this Astrozap dust cover for your 8-inch Dobson, your telescope will stay clean between observing sessions.

For example, do you have a Skyliner-200P Dobson, Then measure the outer diameter of your tube, so you are sure the cover fits. This applies to any 8-inch Dobson, because the sizes vary per model merk.

A clean mirror doesn’t need to be cleaned as often, which is nice, because you’d rather clean your mirrors as little as possible. If your telescope has caught some dew after an evening outside, let it air dry first before you put the cover on it. If you still need to clean it, see cleaning and maintenance.

For a larger Dobson there is the cover for 10 inch Dobsons.
