Ever gazed up at the night sky and wished you could get a closer look at those distant twinkling stars? You're not alone. 

Many of us have been captivated by the wonders above, and a telescope can be the key to unlocking those mysteries. But with so many options out there, where do you even begin?

Don't fret. In this straightforward guide, we'll walk you through the basic factors to consider before making a choice, helping you find the perfect telescope to start your stargazing journey. 

No jargon, no fuss – just a simple path to clearer skies and breathtaking views.

Factor #1: The aperture size

The aperture of a telescope is the diameter of its main optical component, which can be either a lens or a mirror. This component gathers light, and the larger the aperture, the more light the telescope can collect, making it more capable of providing a detailed view of faint and distant objects.

Factor #2: Its magnification power

It's a common misconception that magnification is the most important factor. Actually, a high magnification is useless without a large aperture as it will just magnify the blur. Magnification can be changed by using different eyepieces, so it's not a fixed feature of the telescope itself. The maximum useful magnification for a telescope is usually considered to be 50 times the aperture in inches (or twice the aperture in millimetres).

Factor #3: The type of mount

The mount is critically important as it holds the telescope and allows you to point it at different parts of the sky. There are two main types: altazimuth and equatorial. Altazimuth mounts move up/down (altitude) and left/right (azimuth), while equatorial mounts are set up to follow the rotation of the sky. For astrophotography, an equatorial mount is generally necessary.

Factor #4: Its Portability

Depending on your lifestyle and where you plan to use the telescope, size and portability can be important considerations. Some larger, more powerful telescopes are not easily transportable, while smaller ones can be packed up and taken on trips.

Factor #5: Its Type of Telescope

There are three basic types: Refractors, Reflectors, and Compound or Catadioptric telescopes. Each has its own advantages and drawbacks. For example, refractors are good for viewing planets and the moon, while reflectors are usually better for deep-sky objects.

Factor #6: Its Cost

Telescopes can range greatly in price, from less than £100 to several thousands of pounds. More expensive models often have larger apertures, more advanced mounts, or more sophisticated electronic controls. Determine your budget ahead of time, and keep in mind that you may also need to purchase accessories like eyepieces, filters, and star charts.

Factor #7: Its intended use

What do you want to observe? The Moon, the planets and comets? Deep-sky objects such as galaxies and nebulae? Or a bit of everything? Also, do you want to do astrophotography or just visual observing? Your answers to these questions will influence the best telescope for your needs.

Factor #8: Your Experience Level

Some telescopes are more user-friendly than others. For beginners, a simple, easy-to-use telescope is usually the best choice. As you gain experience and knowledge, you might choose to upgrade to a more complex system.

Factor #9: The accessories its coming with

These include finders, eyepieces, filters, Barlow lenses, motor drives, and more. Some are essential, some are optional, and they range widely in quality. Check what comes with the telescope and what might need to be purchased separately.

Factor #10: The Brand and User Reviews

Lastly, it's worthwhile to check the brand and the reviews of the telescope you're planning to buy. Make sure you're purchasing from a reputable company, and read reviews to get an idea of the user experience and any potential problems. Some well-known brands include Celestron, Orion, and Meade.
