Collection: Celestron Nexstar 8SE Best Accessories

Greetings, fellow stargazers! If you're diving into the mesmerizing world of astronomy with your Celestron NexStar 8SE, congratulations on choosing an exceptional telescope. To enhance your cosmic journey, let's explore the must-have accessories recommended by seasoned astronomers and enthusiasts.

Power Supply: The Core Necessity

One recurring theme is the importance of a reliable power source. While the NexStar 8SE can run on AA batteries, many users emphasize the convenience and longevity of a dedicated power supply. The Celestron PowerTank or an equivalent 12V lithium-ion battery pack comes highly recommended for extended sessions without the hassle of frequent battery changes.

1. Lithium Battery Pack for Portability

A portable 12V lithium-ion battery pack provides a reliable and portable power source. It's particularly useful for off-grid observations and minimizes cord interference.

2. External Power Options

Explore external power options, such as AC adapters and 12V battery packs, to avoid relying solely on disposable batteries. Ensure compatibility with your telescope model.

Eyepieces and Filters: Seeing the Universe Clearly

One of the first considerations for NexStar 8SE owners is upgrading eyepieces. The telescope comes with a starter set, but experienced users often prefer a more personalized collection. Here are some recommendations based on expert advice and user experiences:

Recommended Eyepieces:

  1. 8-24mm Celestron Zoom Eyepiece: Users rave about its versatility, replacing an entire set of fixed focal length eyepieces. Ideal for both beginners and experienced astronomers, offering a range of magnifications.
  2. 12mm Illuminated Reticle Eyepiece: Useful for precise alignment and locating objects in the night sky.
  3. 40mm Plossl Eyepiece: Provides a wide field of view, enhancing the observation of larger celestial objects.

Eyepieces: Enhancing Your Celestial Views

1. Zoom Eyepiece for Versatility

The 8-24mm Celestron Zoom Eyepiece is frequently lauded for its versatility, replacing multiple fixed focal length eyepieces. This accessory provides a range of magnifications, making it ideal for various celestial objects.

2. Illuminated Reticle Eyepiece for Precision

Consider adding a 12mm Illuminated Reticle Eyepiece to enhance your alignment accuracy. This is especially useful for astrophotography, ensuring your telescope is precisely positioned.

3. Wide Field Eyepiece for Deep Sky Observations

For wide-field views, the ES68 24mm eyepiece is recommended. Its expansive field of view is perfect for capturing deep-sky objects like nebulae and galaxies.

4. Additional Eyepieces for Varied Magnification

Invest in eyepieces with focal lengths of 32mm, 18mm, and 10mm to cover a range of magnifications suitable for different astronomical targets.

5. Quality Diagonals for Clearer Views

Consider upgrading your diagonal for improved image quality. The 1.25" diagonal shipped with the SCTs is functional but may be worth upgrading for enhanced performance.

Filters: Enhancing Specific Observations

Filters can significantly improve your observations by enhancing contrast and reducing glare. While personal preferences vary, here are some general recommendations:

1. Moon Filter for Lunar Observations

A lunar or Moon filter is crucial for lunar observations, reducing the brightness and enhancing details on the moon's surface.

2. Light Pollution Filter for Urban Observers

If you observe from light-polluted areas, a light pollution filter can help improve visibility by reducing the impact of artificial lights.

3. Solar Filter for Safe Solar Observations

For solar viewing, invest in a solar filter. The Baader Astro Solar Film is a reliable choice for safely observing sunspots and solar events.


While opinions on filters vary, a lunar/Moon filter is commonly suggested to reduce glare during lunar observations. Some users also recommend exploring additional filters for specific astrophotography purposes, but they may not be deemed essential for general observing.

Mount Accessories: Improving Stability and Alignment

1. Dew Shield for Preventing Dew Formation

Dew can be a persistent issue during nighttime observations. Invest in a dew shield to minimize dew formation on the corrector plate.

2. Cradle and Mount Accessories for Convenience

Consider a 3D-printed handset cradle for convenient storage, and explore options for mounting your battery pack securely on the telescope's arm or tripod.

3. GOTO Alignment Tools for Precision

For precise GOTO functionality, explore tools like StarSense AutoAlign. These accessories contribute to accurate alignment and efficient tracking.

Additional Accessories for Comfort and Efficiency

  1. Observing Chair: Investing in a comfortable observing chair, such as the ones recommended by seasoned astronomers, can significantly enhance your overall stargazing experience.

  2. Dew Shield and Heater Strips: Controlling dew on the telescope's optics is crucial, especially in humid conditions. A dew shield and heater strips, powered by your 12V supply, can help maintain clear views.

  3. Red LED Light: Preserving your night vision is key. A red LED light allows you to read star charts or adjust equipment without disrupting your eyes' adaptation to the darkness.

Aligning and Controlling Your Scope

  1. Upgrading Firmware: Ensure your telescope's firmware is up-to-date for optimal performance. Regularly updating the firmware is a simple yet effective step in maximizing your telescope's capabilities.
  2. SkyPortal or SkySafari App: Consider using astronomy apps like SkyPortal or SkySafari for aligning and controlling your telescope. This modern alternative can enhance your user experience, providing a seamless connection between your smartphone or tablet and the telescope.
  3. StarSense AutoAlign: For completely automatic alignment, some users recommend considering StarSense AutoAlign. Check compatibility with your scope model for hassle-free alignment.

Additional Considerations: Comfort and Learning Resources

1. Comfortable Observing Setup

Invest in an observing chair and a folding table to enhance your comfort during extended observation sessions. Comfort is key to enjoying your time under the stars.

2. Educational Resources for Astronomy Enthusiasts

For those new to astronomy, educational resources like "Turn Left at Orion" provide valuable insights into observing techniques, celestial objects, and the night sky.

3. Collimation Tools for Optimal Performance

If you're interested in optimizing the performance of your Celestron NexStar 8SE, consider acquiring collimation tools, such as a good-quality Phillips head screwdriver.


Armed with these insights from seasoned astronomers, you're well-equipped to optimize your Celestron NexStar 8SE experience. Remember, astronomy is a journey of discovery, and each accessory you choose enhances your ability to explore the wonders of the night sky. Happy stargazing!
