Celestron NexStar Evolution 8 (8" 203 mm f/10 SCT, GOTO, SKU: 12091)

The NexStar Evolution series by Celestron is a groundbreaking line of telescopes designed for nocturnal observation enthusiasts. Packed with advanced features and cutting-edge technology, these telescopes offer an unparalleled stargazing experience.

One of the notable upgrades in the NexStar Evolution series is the completely redesigned alt-azimuth assembly. Equipped with new, high-precision motors and worm gearboxes on both axes, these telescopes provide enhanced accuracy and smoother tracking compared to the classic "NexStar" models.

With the dual-axis encoder system and ergonomic control knobs, users can manually rotate the telescope without losing their orientation towards celestial objects. This innovative feature significantly reduces the margin of error in object searching and tracking.

The built-in lightweight lithium-ion battery is another remarkable feature of the NexStar Evolution telescopes. This efficient battery can operate for up to 10 hours, even in winter conditions, eliminating the need for external power sources and cumbersome cables. Additionally, seamless compatibility with the Starsense AutoAlign system further enhances the convenience and functionality of these telescopes.

However, the most revolutionary aspect of the new NexStar Evolution series is the wireless control capability. Users can now control the telescope wirelessly through WiFi using their smartphones. Celestron provides a dedicated software application that enables users to operate the telescope effortlessly. The software offers a multimedia-rich interface, providing a realistic representation of the night sky at any given time.

Another noteworthy feature is the red illuminated accessory tray. This convenient tray includes three eyepiece slots (1.25" and 2") and space for various small accessories. Interestingly, it can also be used with partially folded tripod legs, adding to its versatility.

Key Features of the Evolution Series:

• Built-in WiFi: The telescope can be operated wirelessly without the need for a traditional GoTo controller. Users simply need to install the provided software on their smartphones or tablets to control the telescope through a wireless network.
• Free Celestron Software: The included software offers a realistic sky representation, advanced features, and extensive information about celestial objects. It predicts significant events such as the visibility of the Great Red Spot on Jupiter, moon transits, and various object phenomena like conjunctions, occultations, and sunsets. The program also provides recommendations for observing interesting nebular objects and showcases them with stunning photos.
• Long-Life Lithium-Ion Battery: The telescopes feature a rechargeable lithium-ion battery that provides up to 10 hours of continuous operation. The battery's exceptional performance ensures extended observing sessions.
• Precision Gears and Upgraded Motors: The NexStar Evolution series incorporates precisely crafted gears and modified motors, enabling highly accurate tracking. Both the azimuth and altitude axes utilize worm gears, minimizing backlash and significantly improving performance compared to the previous SE series.
• SkyAlign: Setting up the telescope is made easy with the SkyAlign feature, which relies on aligning the telescope using three bright stars instead of referencing the entire sky.
• Included NexStar+ Controller: While the telescope's full functionality can be accessed through WiFi control, Celestron also includes their traditional NexStar+ controller for additional options and flexibility.
• Improved Tripod: The tripod is constructed entirely from metal components, greatly enhancing its stability and load-bearing capacity. The tripod legs feature multiple markers for easy leveling at different heights.
• Quick Folding and Unfolding: The telescope components can be quickly assembled or disassembled using user-friendly screws with large handles. No additional tools are required, making setup and teardown effortless.
• 4 AUX Ports: The Evolution series includes four AUX ports that allow users to connect additional devices to the mount. Particularly useful is the port for the StarSense system, enabling automatic alignment.
• Included Power Supply: Each telescope comes with a universal mains adapter capable of accommodating various supply voltages and plug types. The power supply parameters are 12V 2.1A.
• Accessory Tray: The telescopes feature a convenient accessory tray that can accommodate three eyepieces (1.25" and 2") and other accessories. The tray does not need to be removed when folding the tripod legs.
