Powerful Newtonian system telescope mounted on a Dobsonian mount with a 25 cm aperture. Offers high-brightness performance ideal for observing nebulae and other deep-sky objects under dark skies. The large aperture also delivers detailed planetary and lunar views within the Solar System.
Equipped with a Pyrex mirror
Every Sky-Watcher Dobson telescope features mirrors crafted from PYREX glass, known for its minimal thermal expansion and superior image quality compared to standard glass mirrors.
Features a collapsible design
Telescope assembly utilizes sliding tube components, eliminating the need for tools or separating the tube into multiple sections. Ready for use in seconds, the precision-engineered mechanism removes the requirement for frequent collimation after each setup.
Contains a optical system
Built using the classic Newtonian system, the primary parabolic mirror offers a 250 mm diameter and a 1250 mm focal length, with a high-brightness f/5 configuration.
Fitted with a mount
Mounted on a Dobsonian azimuth mount, the design ensures simple, stable rotation on both azimuth and altitude axes. The fork mount supports both sides of the telescope while the upper section rotates smoothly on the base. Low center of gravity and robust materials guarantee enhanced stability over traditional equatorial mounts.
Equipped with a focuser
Features a 2" eyepiece focuser, including a 1.25" adapter. The Crayford-style focuser operates smoothly and precisely, supplied with a 2" extension and a 1.25" extender/reducer, which should be used individually. Fully compatible with autofocusers from Sky-Watcher.
