Τηλεσκόπιο Skywatcher Esprit 100mm F/5 OTA

The Skywatcher Esprit 100mm F/5 OTA is a remarkable telescope designed specifically for astrophotography and advanced visual observations. With its 100 mm aperture and 550 mm focal length, this telescope boasts a fast focal ratio of f/5.5, making it ideal for capturing wide-field images and allowing quicker exposures.

One of the standout features of this model is its three-element, air-spaced objective lenses made from premium optical glass. Equipped with an ED (Extra-low Dispersion) FPL-53 glass element, the lenses are fully multi-coated to enhance clarity, sharpness, and contrast while effectively eliminating chromatic aberration.

The telescope's design also includes a dedicated two-element field flattener, which corrects edge distortion, ensuring that stars remain sharp all the way to the edges of the image frame, supporting a flat-field imaging across a 40 mm image circle.

Additional features include:

• Maximum useful magnification: 183x to 236x, typically accepted near 197x for visual use.
• Limiting stellar magnitude: 12.5, allowing the observation of faint celestial objects.
• Optical tube: Rolled steel construction with a glossy white finish, ensuring durability and aesthetic appeal.
• Weight: Approximately 16.3 pounds (6.3 kg), balancing portability with performance.

For astrophotographers, the 3.4-inch dual-speed rack-and-pinion focuser facilitates precise focusing, essential for capturing detailed astrophotos. It features roughly 69 mm of back focus, accommodating heavy imaging equipment effortlessly. This telescope comes with a comprehensive accessory set, including:

• 8x50 right-angle erect-image finderscope
• 2-inch dielectric diagonal
• M48 camera adapter
• Padded hard carrying case

In conclusion, the Skywatcher Esprit 100mm F/5 OTA is engineered for those who value high-quality imaging in astrophotography, combining premium optics with superb functionality.
