Rainband for 1.25 inch eyepieces and 50 mm finders | Astrozap

Your eyepiece often gets fogged by your own breath or because it has been left outside in the cold for a while. With this Astrozap fogging band for a 1.25 inch eyepiece, you prevent that. You put the band around the eyepiece or around a 50 mm viewfinder, and the slight heat keeps the glass just above the fog point.

A 50 mm viewfinder, like your telescope, points upwards and therefore also has to deal with considerable fog. If you want to know more about eyepiece sizes and magnification, read on. our explanation about eyepieces.

Connect the hose to a fog regulator, such as The two-channel controller. Place it close to the lens that you want to keep free and do not raise the regulator above what is necessary.

For eyepieces with a 2 inch barrel there is a wider tire for 2 inches.
