On a viewfinder that is outside, dust and moisture quickly accumulate, and then you see less when you are looking at objects. A cover for your 9×50 viewfinder prevents that. The TG-FC from Telegizmos goes over the viewfinder, so that the lens and eyepiece remain clean and dry.
A 9×50 viewfinder is a small viewer on your telescope with 9 times magnification and a lens of 50 mm, like the 9×50 viewfinder with mount from Sky-Watcher. It helps you find objects before you look through the main telescope.
When choosing your viewfinder, pay attention to its shape: a straight viewfinder and a diagonal viewfinder have different shapes, so compare the dimensions with your viewfinder. You can find other models at our seekers and visionaries.
There is a contraindication during observation in case of dew. rainband for 50 mm searchers.
