If you have been using a telescope for quite some time already, you will start to realize the cons that come with the lower-end models. Those entry-level variants won’t fit your standards anymore, probably because they have poor magnification or not-that-good image quality.

That is why investing in a professional telescope is a good call.

What is a professional telescope for?

A professional telescope allows you to observe celestial bodies with few limitations while offering quality, clarity, and power for a deep space exploration experience.

To make the viewing experience better, buying a telescope designed for a specific purpose is a great idea. For instance, if you want good magnifying power, then choose a telescope with a high focal length.

The specs you should look for in a telescope depend on your needs.

How does a telescope work?

A telescope collects light to help you see the fine details of heavenly bodies. The method of light-collection varies for each model. It is important to know first how a telescope works before you decide to purchase one.

Types of telescope designs

The most common telescope designs are refracting, reflecting, and catadioptric.

Refracting design

  • Unlike telephoto lenses
  • Uses various optical glass elements for image focus captured at the front end

Reflecting design

  • Longer and heavier
  • More light-gathering power
  • No large, and objective lens made of glass in front
  • Does the job will hollow tubes with big parabolic reflecting mirror
  • The mirror is located in the back, which reflects image up to the tube’s front
  • Image is reflected through Newtonian, Schmidt or Maksutov Cassegrain’reflector

Newtonian reflector: 

  • A secondary mirror reflects the image to the telescope side’s eyepiece

Schmidt Cassegrain’s reflector: 

  • The image has reflected the eyepiece at the back, situated in a conventional position, straight down the tube through the main mirror’s hole

Maksutov reflector: 

  • It is a hybrid with a front glass lens for light focus. It works like a camera’s ‘catadioptric’ mirror lenses

Catadioptric design

  • Uses both lenses and mirror
  • Comes in Schmidt-Cassegrain and Maksutov-Cassegrain variants

What does a professional telescope offer?

Professional telescopes are generally more expensive, but it gives value for money because of their advanced and premium features.

That is why professional telescopes are mostly used by professional astronomers, teachers, and astrophotography artists because of the ultimate and convenient experience it provides.

These telescopes have a great viewing experience and, most of the time, are apochromatic. To maximize its features, make sure that you know how to use it well.

Hence, it is not ideal for beginners. Its hefty price also demands careful care and maintenance—from water and dust safety to mount security.

Does a bigger telescope mean that it is also better?

Yes, if it is in the case of light-gathering capabilities. A higher aperture allows you to gather more light, and more light means higher image quality, especially for faint objects.

For instance, a four-inch mirror has better light-gathering capability than a two-inch variant.

A guide to choosing the best professional telescope

Aperture size

The higher the aperture, the better. Hence, if you are looking for a professional telescope, choose one with great aperture size. Lower apertures will have difficulty showing deep-sky objects, even if your optics are great.

Focal length and magnification

The focal length will determine the scope of what you plan to view, whether it is planetary or deep sky exploration. Before choosing which focal length suits you, determine first what you plan to use your device for.

In terms of magnification, the focal length plays a role along with the eyepiece. More magnification is better, but you must also consider if the image magnified is cleared, otherwise, the high magnification is just useless.

Type of mount

The mount type you should choose depends on whether you want a portable one or one used indoors or stationery. Another consideration is if you want a manual set-up or one you can control with a device such as a computer.

Some types of mounts you can consider are equatorial, Dobsonian, and Alt-az. Before you decide, make sure that you know what your needs and preferences are.

Quality of optics

Optics quality is important to get a clear view without the unnecessary dents and bends caused by dust and other elements. For added dispersion, you should choose apochromatic lenses because they contain liquid between each lens.

How to maintain your new telescope

In order for your newly-bought telescope to last long, it needs proper maintenance.

  • Clean the optics so that you can see the celestial bodies with clarity.
  • Do preventive maintenance to limit light distortion caused by dust accumulation on the mirror and lenses.
  • Choose a model with a protective cap, or make your homemade cap, to protect the lens from dust.
  • When not in use, position the scope downward to prevent dust accumulation in the optics.
  • Store the extra eyepieces in a plastic bag.
  • Refrain from touching your telescope’s mirrors and lens.

How to clean your telescope’s mirror or lens

  • To remove dust, you can use a camel-hair brush.
  • You may also buy cleaning products from stores that sell various cameras.
  • In case of spillage, use a special solution to clean it, such as pure methanol.
  • For reflector telescopes, make sure that you know how to disassemble and assemble them.


Which of these brands—Celestron, Meade, and Orion, is the best?

Some well-known brands sell their products for a high price without great quality, just because they rely on their reputation. When buying telescopes, do not look at the brand.

Focus on the specs instead. That way, you get value for your money.

How much does a telescope cost?

You can buy a decent one for just 100 dollars. If you want to buy something of better quality, you can raise your price point a little bit to 150 to 200 dollars.

Will a telescope allow me to see galaxies?

Depending on your environmental conditions, such as light pollution, and sky conditions and, your telescope’s aperture, the quality of your image will vary. At the very least, you would be able to see the Andromeda Galaxy.

Are Dobsonian telescopes the best?

Dobsonian has a simple construction, plus they are affordable, easy-to-use, and portable. It also does not have complicated equatorial coordinates and smooth and simple motions, making it user-friendly.

Regarding image quality, it has a reflector optical design for maximum aperture while having no issues with chromatic aberration. That is why Dobsonian telescopes are popular and are considered the best.

What is a small, medium, large, and very large telescope?

These labels refer to their sizes.


  • The aperture of 6 inches or less
  • In astronomical terms, an aperture of 8 inches or less


  • The aperture of 8” to 13.1.”
  • Can fit in an automobile
  • Needs truss tube for one-person handling


  • A vague term
  • It can have an aperture of 14” to 22.”

Very large

  • The aperture of 22” above
  • Not manageable by one person
  • Cost around 10 000 dollars or more
  • It can sometimes fit in a regular truck


Your budget and preferences determine the model of professional telescope you should go for. Before you purchase a telescope, make sure that you have already decided if you want a portable type or not and what kind of celestial bodies you would always want to view.
