To aim your Telescope, you first need to collimate it, then find the object, center your target object in the view of your Telescope, and adjust the focal length, the elevation, azimuth knobs, and the diopter. After you’ve done that, your aim will be accurate, and you’ll be able to see the object you’re looking for.

Like most people, you probably think that learning to aim a telescope is some sort of dark art. You may have visions of complex calculations and measurements that need to be made to point your Telescope at the right spot in the sky.

In reality, learning how to aim a telescope is much simpler than you might think.

In this blog post, I will walk you through 10 simple steps that will make it easier for you to aim your Telescope accurately.

How To Aim a Telescope |7 Steps to Make It Easier for You

Read on for a step-by-step guide on how to aim your Telescope.

Step One: Collimate Your Telescope

If you want to ensure that your Telescope is aimed accurately, the first step is to collimate it. Collimating a telescope simply means aligning the optics to point in the same direction.

This is important because even a small misalignment can cause large errors in your aim.

There are a few different ways to collimate a telescope, but the most common method is to use a collimating eyepiece. This is a special eyepiece with crosshairs in the center that you can use to line up your Telescope’s optics.

If you don’t have a collimating eyepiece, don’t worry – you can still collimate your Telescope without one.

Step Two: Find Your Target Object

The next step is to find your target object. This is the object that you want to point your Telescope at.

There are a few different ways to find your target object. These include:

Star chart: This night sky map shows you where to find different objects.

Planisphere: This rotating star chart allows you to set the date and time to see where objects will be in the sky.

Computer software: Various computer programs can help you find objects in the sky.

SkySafari or Stellarium: These apps can help you identify objects in the sky and tell you where they are located.

Step Three: Center Your Target Object in The Telescope’s Field of View

The next step is to center your target object in the Telescope’s field of view. There are a few different ways to do this, but the most common method is to use the finder scope.

The finder scope is a small telescope mounted on the side of the main Telescope. It has a much wider field of view than the main Telescope, which makes it easier to center objects in the main scope.

Point the finder scope at the object to center your target object in the main scope. Then, look through the finder scope and adjust the position of the main scope until the object is centered in its field of view.

Step Four: Adjust The Focal Length

Once your target object is centered in the main scope, the next step is to adjust the focal length. The focal length is the distance from the main lens or mirror to the point where the image is formed.

Changing the focal length will change the magnification of your Telescope, so it’s important to get it right. For most objects, you will want to use a medium level of magnification.

First, locate the focus knob on your Telescope to adjust the focal length. Then, turn the knob until the image is clear and sharp.

Step Five: Adjust the Elevation And Azimuth Knobs

The next step is to adjust the elevation and azimuth knobs. The elevation knob controls the up and down movement of the Telescope, while the azimuth knob controls the left and right movement.

To adjust the elevation and azimuth:

  • Loosen the knob until it is loose enough to move freely.
  • Then, point the Telescope up or down until your target object is in the center of the field of view.
  • Finally, tighten the knob to lock the position in place.

Step Six: Adjust the Diopter

The next step is to adjust the diopter. The diopter is a knob that is located near your eye when you are looking through the Telescope.

It is used to fine-tune the focus of the eyepiece.

To adjust the diopter, first look through the Telescope and find something far away that has fine details (like a tree branch or the edge of a building). Then, turn the diopter knob until the details are sharp and clear.

Step Seven: Enjoy the View

Once you have followed all of these steps, you should be able to see your target object clearly through the Telescope. Take some time to enjoy the view and look for other interesting objects in the sky.

When you are finished, remember to turn off the Telescope and cover it up to protect it from the elements.

How to Get the best Out of Your Telescope

Before you start observing, there are a few things you need to do to get the best possible view:


Make sure you set up your Telescope in a location with little or no light pollution. The best place to observe is away from city lights, under a dark sky.

If you live in an area with light pollution, there are still ways to get a good view. One option is to drive out of town and find a dark spot.

Another option is to use a light pollution filter, which will help reduce the amount of light pollution in your field of view.


Another factor that can affect your view is the temperature. When it’s colder, the air is denser, and this can cause objects to appear fuzzy.

The best way to combat this is to dress warmly and make sure the Telescope is in a sheltered spot.

If you can, try to set up your Telescope in an area with some airflow. This will help to keep the air around the scope moving and reduce the chances of seeing fuzzy objects.

Invest in a Good Lens

If you want to get the best possible view, it’s worth investing in a good-quality lens. A telescope with a low-quality lens will produce fuzzy images, even if everything else is perfect.

There are a few things to look for when choosing a lens:

  • The focal length should be at least 1000mm.
  • The aperture should be at least 100mm.
  • The lens should be made of glass, not plastic.

With a good quality lens, you’ll be able to see much more detail in your target objects.

Things to Keep in Mind as You Aim a Telescope

Now that you know how to set up and aim your Telescope, it’s time to start observing.

There are a few things to keep in mind when you’re using your Telescope:

  • The best time to observe is during the darkest hours of the night. This means that you should avoid observing during twilight (when the Sun is close to the horizon) and during the daytime.
  • The Moon can be very bright and wash out faint objects in the sky. For this reason, it’s best to observe when the Moon is not up.
  • Some objects are only visible for a short period of time, so it’s important to know when they will be visible. This information can be found in astronomy books and magazines or online.
  • Finally, don’t forget to take your time and enjoy the view. There is no rush when you’re observing the night sky. Take your time and look for interesting objects.

With a little practice, you’ll be an expert at using your Telescope in no time.

Aiming a Telescope FAQs

How do I know if my Telescope is properly aligned?

The easiest way to tell if your Telescope is properly aligned is to look at a bright object like the Moon or a planet. If the object looks fuzzy, your scope is probably not aligned correctly.

How do I know where to point my Telescope?

There are a few ways to find out where to point your Telescope. One way is to use a star chart.

These charts show the positions of objects in the sky and can be used to help you find your target.

Another way is to use an app like SkySafari or StarWalk. These apps will show you the positions of objects in the sky in real time, making it easy to find your target.

Why can’t I focus my Telescope?

Most refractors rely on the star diagonal to focus. If your star diagonal is not properly positioned, you will not be able to focus on your Telescope. Make sure the star diagonal is in the correct position before attempting to focus.

Final Thoughts

Aiming a telescope doesn’t have to be difficult. You just need to know what you’re doing and be patient.

Start by finding a dark spot to set up your scope. Then, use a star chart or app to find your target object.

Once you’ve found it, focus on the scope and enjoy the view. With a little practice, you’ll be an expert at using your Telescope in no time.
