The Celestron NexStar 4 SE Telescope, model number 11049, is an excellent choice for astronomers who are just starting their celestial journey or for those who are looking for a portable and powerful instrument. This telescope comes as a demo or refurbished model, ensuring that it still delivers high-quality performance while being more affordable than a brand-new unit.
The NexStar 4 SE features a compact and sturdy design, with its alt-azimuth mount providing smooth and accurate tracking for both celestial objects and terrestrial targets. This telescope boasts a 90mm (3.5 inches) aperture and a focal length of 910mm (36 inches), providing a generous 102x magnification when using the included 9mm eyepiece. This magnification level is sufficient for observing craters on the moon, Jupiter's moons and bands, and even the rings of Saturn.
The Schmidt-Cassegrain optical design of the NexStar 4 SE offers several advantages. First, it provides a wide field of view, allowing you to easily locate objects with the supplied 5x24 finderscope. Second, it offers excellent light-gathering capability, which is crucial for observing fainter deep-sky objects. Lastly, it offers a nearly parabolic primary mirror, ensuring that the images you see are sharp and free of aberrations.
The NexStar 4 SE also comes with a database of over 40,000 celestial objects, which can be accessed using the included NexStar hand controller. The controller includes a built-in telescope alignment procedure, making it easy to set up and begin observing right away. The telescope can be powered using eight AA batteries (not included), or you can opt to use a DC power adapter (sold separately).
Additional features of the NexStar 4 SE include a dual-speed 10:1 focus mechanism for fine-tuning your focus, a 1.25-inch star diagonal for brighter images, and a 1.25-inch visual back for using eyepieces or other accessories. The telescope comes with a StarPointer finderscope, two eyepieces (25mm and 9mm), and a collimation cap for ensuring optimal performance.
In conclusion, the Celestron NexStar 4 SE Telescope, model number 11049, is a powerful and versatile instrument that delivers impressive views of celestial objects. Its compact size, ease of use, and rich feature set make it an excellent choice for both beginners and experienced astronomers.
