Understanding Your Celestron Telescope

Celestron telescopes are renowned for their quality, precision, and variety of models, where each design caters to different levels of astronomical interest and expertise.

The key components of your Celestron telescope include:

  • Optical tube
  • Eyepieces
  • Finderscope

Each component plays a vital role. The optical tube houses the primary lens or mirror, which gathers light from celestial objects. The size and type of this optical element determine the telescope’s ability to capture faint objects and provide sharp views.

The mount supports the optical tube and allows smooth movement for tracking. It’s important to understand how to balance and align the mount for stable and accurate observations.

Eyepieces are interchangeable lenses that magnify the image produced by the optical tube. There are different eyepieces and each determines the magnification levels. The magnification level determines how well you can zoom in on planets or how broad a view of star clusters can you get.

The finder scope is a smaller scope mounted on the main tube and its purpose is to help you locate objects in the night sky before viewing them through the eyepiece.

It’s important to familiarize yourself with these components and see how they interact together. This will enhance your ability to navigate the night sky.

Therefore, we highly recommend spending time learning how to set up, align, and use your Celestron telescope. By taking time now, you’ll be rewarded later on with breathtaking views of the cosmos.

Needless to say, your stargazing sessions will be a truly immersive experience. Also, congratulations on choosing Celestron - they won’t ever disappoint!

Setup and Use

Now that you’re familiar with a Celestron telescope, it’s important to note that there is a series of steps that you need to follow to set it up for the first use.

These steps include:

  • Unboxing and initial setup
  • Mounting the optical tube
  • Balancing and aligning
  • Using eyepieces and focusing

Unboxing and Initial Setup

Unboxing and initial setup require you to carefully unbox all components and lay them out on a flat surface. Ensure that all parts are present, including the optical tube, mount, tripod, eyepieces, and finderscope.

Assemble the tripod by ensuring it stands on a stable, level surface. Extend the legs to a comfortable height and secure them in place.

The next thing you have to do is attach the mount to the tripod. Also, always follow Celestron’s instructions for attaching and securing the mount.

Mounting the Optical Tube

To mount the optical tube, carefully place it onto the mount by ensuring it’s securely fastened. Most Celestron telescopes use dovetail bars for this purpose, which allow you to slide the tube into place and tighten it down.

When you mount the tube, attach a finderscope to its bracket. The finder scope is crucial to locate objects in the sky.

Balancing and Aligning

Before the first use, you should also balance it for smooth operation. If you have an equatorial mount, you need to balance it on both the right ascension and declination axes. To do this, loosen the RA clutch and adjust the counterweight until the telescope remains stationary. Repeat the same process for the DEC axis.

Alignment is the next critical step. Alt-azimuth mounts are good with only a simple two-star alignment. However, equatorial mounts require polar alignment.

To do this, point the RA axis towards Polaris, the North Star using a polar scope (if available). This alignment will ensure your telescope tracks objects accurately when they move across the sky.

Using Eyepieces and Focusing

We highly recommend starting with low-power eyepieces for initial observations as they provide a wider field of view, which helps you easily locate objects.

Insert the eyepiece into the focuser and secure it. Then, use the finderscope to center your target in its crosshair. Look through the main eyepiece and adjust the focus until the object is sharp.

When centered, switch to higher magnification eyepieces for detailed observations.

Observing Tips


When you finally set up your Celestron telescope, it’s important to pay attention to a few important observational things. These include:

  • Cooling time
  • A star chart or app use
  • Light pollution
  • Patience

Telescopes need to reach thermal equilibrium with the outside temperature before they can deliver clear images. Therefore, set up your telescope outside at least 30 minutes before observing.

If you’re starting, you can help yourself with a star chart or an app to locate celestial objects. They serve as a roadmap of the night sky and they can make your sessions much more productive and enjoyable.

It’s also important to avoid light pollution, so try and find a dark location away from the city lights to improve your viewing experience. Even a small amount of light pollution will impact the visibility of faint objects.

Lastly, it’s important to be patient. Observing celestial objects requires patience so allow your eyes to adjust to the darkness and take your time to study each object.


Mastering the setup and use of your Celestron telescope can unlock a world of celestial wonders. From the craters of the moon to distant galaxies, it’s important to follow the detailed steps for assembly, alignment, and observation to achieve optimal performance.

Rewarding stargazing experience is the result that’s worth going through the learning and setup phase.

Embrace the patience and curiosity that astronomy demands and you’ll find that the night sky holds endless opportunities for discovery.
