About this product
The two included 4-element Super Plossl eyepieces are multicoated with a 52° field of view. The 25mm eyepiece yields a comfortable 72x magnification. Using the 10mm eyepiece pushes the magnification to a very capable 180x. A 2" dual-speed Crayford-style focuser enables precise focusing that is hard to match with conventional rack-and-pinion focusers.
One of the defining elements of Dobsonian telescopes is their size. While the large size produces bright high-quality images, transporting them is often difficult. The optical tube assembly (OTA) and the base of this telescope are both collapsible to make it more manageable. The optical tube assembly is designed with three support struts. To collapse the OTA, release the locks and slide the front of the assembly down the struts to rest against the back section. The forks on the base unscrew and come off. With no tools required, this collapsible system offers convenience not normally found in a Dobsonian.
