Key Features:

• Aperture: 76mm (3 inches) – The 3-inch aperture offers a balance between portability and light-gathering power, making it suitable for planetary observations, the Moon, and brighter deep-sky objects like star clusters.

• Focal Length: 480mm – This shorter focal length provides a relatively fast f/6.3 focal ratio, ideal for wide-field viewing. It's perfect for panoramic star fields, comets, and larger celestial objects like the Andromeda Galaxy.

• Optical Design: Triplet Apochromatic Lens System – The triplet lens configuration includes three optical elements that focus light of different wavelengths (red, green, blue) onto the same focal plane. This design virtually eliminates chromatic aberration, resulting in images that are sharp and free of color fringing.

• High-Quality Glass: The Oracle 3 uses premium multi-coated optics to enhance light transmission and reduce glare, providing excellent contrast and clarity, even on faint objects.

• Portability: Weighing only a few pounds and with its compact dimensions, the Oracle 3 is designed for ease of transport. It is a fantastic grab-and-go telescope for astronomers who want to set up quickly and observe on the move.

• Mechanical Construction: Known for its durable and precisely engineered build, the Oracle 3 includes a smooth, dual-speed focuser for fine-tuned focusing, ensuring crisp views.

• Mounting Options: The Oracle 3 is compatible with a variety of mounts, including alt-azimuth and equatorial mounts, making it versatile for both beginners and advanced users.

Ideal Uses:

• Visual Astronomy: The Oracle 3 is ideal for viewing planets, the Moon, and wide-field objects. Its superior optics provide a crisp, color-corrected view that is especially noticeable in high-contrast planetary details like Jupiter’s cloud bands and Saturn’s rings.

• Astrophotography: The fast f/6.3 focal ratio makes it a capable instrument for astro-photographers, especially for wide-field imaging of large deep-sky objects like nebulae or galaxies.

• Portability: Due to its lightweight design, it is highly portable, making it a perfect choice for astronomers who enjoy traveling to dark sky sites.

While no longer in production, the Tele Vue Oracle 3 remains a highly sought-after instrument in the used telescope market due to its outstanding optical performance and build quality. It represents Tele Vue's commitment to producing high-end, well-crafted optical instruments.
