Description

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.
