Description
The GSD 880 Dobsonian Telescope is a powerful and portable Newtonian reflector with a 10" (250mm) aperture and 1250mm focal length, making it an excellent choice for observing deep-sky objects. Despite its impressive size, the telescope's tube is compact enough to fit in a car's back seat, ensuring easy transportation. With high-quality optics and robust mechanics, this telescope is suitable for both beginners and advanced users, delivering exceptional performance for observing nebulae, galaxies, planets, and the Moon.
Advantages at a Glance:
-
High-quality optics: Parabolic GSO primary mirror with 94% reflectivity for brighter and sharper images.
-
Robust construction: Metal optical tube assembly (OTA) with excellent collimation stability.
-
Advanced focuser: 2" Crayford focuser with 1:10 micro-reduction for precise focusing and compatibility with heavy accessories (up to 3kg).
-
Efficient cooling: Primary mirror ventilation ensures faster cool-down of optics.
-
Smooth movement: Innovative friction bearings for altitude adjustment with adjustable resistance and ball-bearing horizontal axis for effortless tracking.
-
Extensive accessories: Includes a 2" 30mm panoramic eyepiece, a 9mm Super Plössl eyepiece, and an 8x50 finder scope.
Applications:
This telescope is ideal for observing the Moon, planets, nebulae, and galaxies but is not recommended for nature observation or astrophotography without additional accessories.
Innovative Mechanics for Smooth Operation:
The telescope features modern roller bearings on the horizontal axis for smooth movement even after years of use. The altitude axis uses robust steel axles with CNC-machined faces for precision adjustments without lateral slip. Resistance can be adjusted via large thumbscrews to suit observing conditions, such as high winds.
Balance Adjustability for Accessories:
The elevation bearing wheels can be repositioned in the rocker box using a precise scale to balance the telescope when switching between heavier or lighter accessories like finders or eyepieces.
Enhanced Observing Experience with Premium Optics and Mechanics:
The GSD 880 Dobsonian delivers exceptional optical performance, robust mechanics, and user-friendly design, making it an excellent choice for beginners and advanced astronomers seeking detailed views of celestial objects in a portable package.
