You’ve just received a Celestron NexStar 127 SLT and you’re wondering what accessories you should buy. That’s completely normal.
The good news? You can start observing right away. The telescope already includes two eyepieces (25mm and 9/10mm) and a full GoTo system.
The key is not buying more — it’s buying the right upgrade at the right time.
Step One: Observe and Learn What You Enjoy
The NexStar 127 SLT is a Maksutov telescope with a 1500mm focal length (f/12). This makes it especially well suited for:
- Moon observation
- Planets like Jupiter and Saturn
- Bright star clusters
Before adding accessories, spend a few weeks using the included eyepieces. You’ll quickly discover whether you prefer:
- High-detail planetary observing
- Wider-field relaxed viewing
- Taking and sharing photos
The First Smart Upgrade: A 5mm Eyepiece
With a 1500mm focal length, a 5mm eyepiece provides:
300x theoretical magnification (realistically 220–250x under good seeing conditions).
This allows you to:
- See more detail on Jupiter
- Better observe Saturn’s ring structure
- Fully use the 127mm aperture potential

Want to Make It Smarter? SkyQ Link 2
The SkyQ Link 2 does not improve optical performance — but it transforms the user experience.
When connected to the Celestron SkyPortal app, you can control the telescope from your smartphone or tablet, select objects directly from a live sky map, and make navigation much more intuitive.
It’s not essential for beginners, but it makes the telescope feel much more modern and interactive.
Taking Your First Photos? Try a Smartphone Adapter
A very motivating accessory is a smartphone adapter.
It won’t replace dedicated astrophotography equipment, but it allows you to:
- Photograph the Moon
- Capture bright planets
- Share your first observing experiences
After a Few Months: If the Passion Grows
Planetary Camera (CMOS)
The NexStar 127 SLT is very capable for planetary imaging with a small CMOS camera.
Stable 12V Power Supply
A reliable power supply improves GoTo accuracy and overall stability.
Common Questions About the NexStar 127 SLT
Is the NexStar 127 SLT good for planets?
Yes. Its long focal length makes it especially effective for lunar and planetary observation.
Is a 5mm eyepiece too powerful?
Only under poor seeing conditions. On steady nights, it’s one of the best upgrades you can make.
Do I need a Barlow lens?
Not at the beginning. A dedicated high-quality eyepiece is usually a better choice.
Can I do deep-sky astrophotography?
Not easily. This telescope is primarily designed for visual use and planetary imaging.
