Αξεσουάρ Τηλεσκοπίων Focal Reducer DO-GSO 0.5x 2"

The Focal Reducer DO-GSO 0.5x 2" is a premier accessory for astronomers aiming to optimize their telescopes. This remarkable device effectively halves the focal length of compatible telescopes, thereby providing a larger field of view and an improved optical speed.

With a nominal reduction factor of 0.5x, the focal reducer allows for a transformation of the telescope's focal ratio from, for instance, f/10 to f/5. This adjustment leads to lower magnification yet wider fields, as well as significantly shorter exposure times for astrophotography.

Key features of the Focal Reducer include:

• Compatibility: Fits any accessory accepting standard 2" threaded filters with M48x0.75 threads.
• Optics: Employs a 2-element fully multi-coated optical system for superior light transmission.
• Physical Dimensions: Total length is 21 mm (0.83 inches) and 16 mm (0.63 inches) excluding external threads.
• Clear Aperture: Measures 37.4 mm (1.47 inches) for ample light throughput.
• Weight: Weighs only 2.4 oz, enhancing portability.

Most suitable for both visual observation and astrophotography, it is particularly advantageous for telescopes with moderate focal ratios and standard eyepieces. This accessory enriches the capabilities of your telescope by offering a balance between a broad field of view and rapid imaging performance.
