PRODUCT FEATURES

| Saxon Dobsonian Telescope DOB-10 |  |  | Code: DOB-10 Comes with the other features of the 8" (like the tension control handle), but yields around 50% greater light-gathering ability.
Features:
The Saxon Dobsonian Telescope 254mm/1200mm (10") have a "paraboloidal" primary mirror to eliminate spherical aberration and a four-arm, secondary- mirror bracket with fine supports (0.5mm thick), to reduce diffraction spikes and light loss. In addition, this model include a 2" focuser with a 1.25" adapter, allowing the use of either eyepiece size. This model also include the new feature-tension control handle.
PYREX GLASS ON THE 10"
The Saxon 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 dameter 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. Available on 254mm/120mm (10") only.
