Pyrex Tube The Sky-Watcher 10” Dobsonian features a primary mirror made of Pyrex glass. Because of its very low coefficient of thermal expansion, Pyrex glass is less affected by changing temperatures. This greatly reduces the cooling time of a telescope larger than 8” in diameter without using an extra fan. The great stability of this low expansion glass ensures high quality images. It is also substantially more resistant to scratching then plate glass.
