Before you start observing the night sky, you’ll need to set up your NexStar 8SE. Follow these steps for a smooth setup process:
1. Unboxing and Inventory Check
When you receive your NexStar 8SE, carefully unbox all the components. The package should include:
Optical Tube Assembly (OTA)
Fork arm mount
Tripod
25mm eyepiece
Star diagonal
Red dot finder scope
Hand controller
Necessary cables and screws
Check that all components are present and in good condition before proceeding.
2. Assembling the Tripod and Mount
Start by setting up the tripod on a stable, level surface. Extend the tripod legs to your desired height and secure them. Attach the fork arm mount to the tripod using the provided screws, ensuring it is tightly fastened to prevent any wobbling during use.
3. Attaching the Optical Tube
Carefully slide the optical tube onto the fork arm mount's dovetail bracket. Secure the tube in place by tightening the clamp. Ensure the optical tube is balanced and secure before moving on to the next step.
4. Attaching the Finder Scope
Attach the red dot finder scope to the bracket on the optical tube. Align the finder scope with the telescope by pointing the telescope at a distant object (like a tree or building) during the day. Adjust the finder scope until the red dot is centered on the object seen through the telescope.
5. Inserting the Eyepiece
Insert the 25mm eyepiece into the star diagonal, and then attach the diagonal to the visual back of the telescope. Tighten the screws to hold the eyepiece securely in place.
6. Powering Up and Initial Setup
The NexStar 8SE requires a power source, either an external battery pack or an AC adapter. Plug in the power source and turn on the telescope using the power switch located on the fork arm. The hand controller will light up, indicating that the telescope is ready for alignment.
Aligning the telescope is a crucial step to ensure accurate GoTo functionality. The NexStar 8SE's SkyAlign technology simplifies this process, even for beginners. Here’s how to do it:
1. Choosing Alignment Stars
Start by choosing three bright celestial objects (stars, planets, or the Moon) visible in the night sky. It’s best to select objects that are widely spaced across the sky.
2. Aligning with SkyAlign
Using the hand controller, enter the date, time, and your location. The NexStar 8SE will use this information to calculate the positions of celestial objects. Next, point the telescope at the first alignment star and center it in the eyepiece using the arrow buttons on the hand controller. Repeat this process for the second and third stars.
Once all three objects are aligned, the telescope will calibrate itself and provide confirmation that alignment is complete. You’re now ready to start observing!
The NexStar 8SE’s computerized GoTo mount allows you to easily locate and track celestial objects. Here’s how to make the most of this feature:
1. Selecting Objects from the Database
The NexStar 8SE comes preloaded with a database of over 40,000 celestial objects. You can use the hand controller to browse through categories like planets, stars, galaxies, and nebulae. Once you’ve selected an object, press the “Enter” button, and the telescope will automatically slew to the object’s location.
2. Fine-Tuning Your View
After the telescope has moved to the object, use the focus knob to sharpen the image. If the object is not perfectly centered in the eyepiece, use the hand controller’s arrow buttons for slight adjustments.
3. Tracking Objects
The NexStar 8SE can automatically track celestial objects as they move across the sky. This feature is particularly useful for long viewing sessions and for keeping objects in view during astrophotography.
The NexStar 8SE is a versatile telescope that can reveal stunning views of a variety of celestial objects. Here are some of the best targets for beginners:
1. The Moon
The Moon is an excellent first target due to its brightness and proximity. With the NexStar 8SE, you can observe the detailed surface features of the Moon, including craters, mountain ranges, and lunar seas. The 25mm eyepiece provides a great balance of magnification and field of view for lunar observation.
2. Planets
Jupiter: View the cloud bands, the Great Red Spot, and its four largest moons (Io, Europa, Ganymede, and Callisto).
Saturn: Marvel at Saturn’s majestic rings and its largest moon, Titan.
Mars: During opposition, you can see surface details like polar ice caps and dark surface markings.
3. Deep-Sky Objects
Orion Nebula (M42): A bright and beautiful nebula located in the constellation Orion. The NexStar 8SE can reveal its swirling gas clouds and young stars.
Andromeda Galaxy (M31): The nearest spiral galaxy to our own Milky Way. You can view its bright core and some of its spiral structure.
Pleiades Star Cluster (M45): A bright open star cluster that is a stunning sight through the NexStar 8SE.
4. Star Clusters
Hercules Globular Cluster (M13): A dense cluster of stars that appears as a fuzzy ball of light in the eyepiece, with individual stars becoming visible at higher magnifications.
Double Cluster (NGC 869 and NGC 884): Located in the constellation Perseus, this pair of open clusters is a striking sight in the same field of view.
To get the most out of your NexStar 8SE, consider these tips:
While the 25mm eyepiece included with the NexStar 8SE is a great starting point, investing in additional eyepieces with different focal lengths can enhance your viewing experience. A 10mm eyepiece, for example, will provide higher magnification for viewing planets and the Moon in greater detail.
2. Avoid Light Pollution
Light pollution from city lights can hinder your ability to see faint celestial objects. Try to observe from a location with minimal light pollution, such as a rural area or a designated dark-sky site.
3. Allow the Telescope to Cool Down
Telescopes can perform better when they have adjusted to the outside temperature. Allow your NexStar 8SE to cool down for about 30 minutes before observing, especially if you bring it outside from a warm indoor environment.
4. Use a Dew Shield
A dew shield is a valuable accessory that prevents moisture from forming on the telescope’s optics, ensuring clear views throughout your observation session.
5. Experiment with Astrophotography
The NexStar 8SE is capable of capturing stunning astrophotographs, especially when paired with a DSLR camera or smartphone adapter. Start with bright objects like the Moon and planets before moving on to deep-sky objects.
The Celestron NexStar 8SE is a fantastic telescope for beginners, offering a blend of powerful optics, ease of use, and advanced features that make exploring the night sky an enjoyable experience. By following this guide, you’ll be well-equipped to set up your telescope, navigate the stars, and discover the wonders of the cosmos.
