How To Buy A Telescope: What You Need To Know Before Taking The Plunge

Are you dreaming of star-gazing but don’t know where to start? Buying a telescope can be an intimidating process. It’s important to know what you’re looking for and the basics on how they work so that you make a purchase you won’t regret. From understanding aperture sizes, to choosing the best type of telescope for your needs, this guide will provide all the information needed before taking the plunge into buying a telescope.

Types of Telescopes

Reflecting Telescopes
A reflecting telescope is a type of optical telescope that makes use of mirrors instead of refracting lenses. These telescopes are made up of two main components: the primary mirror, which captures and reflects light from distant objects; and the secondary mirror, which directs this reflected light toward an eyepiece for observation. Reflecting telescopes have been around for quite some time now, and have many advantages over other types. One advantage is that they allow much larger objective lenses than refractors do – meaning more light can be collected, resulting in brighter images and greater detail being visible. Additionally, since mirrors are less complex to manufacture than lenses, they tend to be cheaper as well! Another benefit is that they don’t suffer from chromatic aberration or coma like some lens-based designs may; thus allowing users to capture potentially sharper images with greater clarity.

Catadioptric Telescopes
Catadioptric telescopes are a hybrid design featuring both curved mirrors (like those found in reflecting telescopes) as well as glass elements (similar to refractors). This combination allows for a compact design with reduced tube length – making them easier to transport and mount on smaller mounts compared to their purely reflective cousins. Catadioptrics also boast excellent image quality due to their ability correct aberrations better than either purely reflective or refractive configurations alone can achieve. Because of these benefits catadioptrics tend be popular among amateur astronomers who need portability but still want high performance optics out in the field!

Radio Telescopes
Unlike most optical designs discussed so far radio telescopes detect electromagnetic radiation at longer wavelengths – such as microwaves or radio waves emitted by astronomical sources such as stars or galaxies far away from us here on Earth! While these types vary widely in size and complexity depending upon how sensitive one needs them to be (and what frequency you’re looking at), all share common principles where an antenna dishes shaped like parabolas collect incoming signals before amplifying it using electronic equipment connected directly into it before processing via computer software algorithms afterwards; allowing scientists & researchers alike access into data never seen before by humans!

Computerized Telescopes

The Advantages of Utilizing Digital Telescopes

Computerized telescopes are becoming increasingly popular tools for amateur astronomers and professionals alike. The ease of use and the advanced capabilities that these digital devices bring to the table make them a great choice for anyone looking to explore and document the night sky with precision. Whether you’re an experienced astronomer or just beginning, there is much to be gained from using a computerized telescope.

One advantage that computerized telescopes offer over traditional telescopes is their ability to precisely locate celestial objects in the night sky with minimal effort on your part. With digital imaging technology, simply inputting coordinates into your device will cause it to automatically identify stars and galaxies in its field of view, eliminating any guesswork that would normally be required when locating faint stars or nebulae manually. Furthermore, many modern models come equipped with GPS tracking systems which can accurately pinpoint their location on Earth at any given time – making sure you never lose your way while searching for new discoveries!

Additionally, computerized telescopes provide unparalleled control over how images are captured during observation sessions as well as automatic exposure stacking which allows users to combine multiple exposures into one image without having to do so manually; lending itself greatly towards capturing high-quality shots of deep space phenomena such as nebulae, star clusters and galaxies far away from our own Milky Way galaxy. This makes it possible for even novice stargazers to take stunning pictures of distant regions in space – something not easily achievable without a digitally operated telescope!

  • Precisely locate celestial objects
  • GPS tracking systems.
  • Unparalleled control over images.


Finally, utilizing an automated telescope greatly reduces fatigue associated with long observing sessions by automating basic functions such as adjusting focus levels or pointing towards target areas – allowing you more free time observe instead of spending all night fiddling around trying different things only marginally adjust settings. Overall this adds up significantly reducing overall observatory costs due lower power consumption rates compared manual driven scopes while still providing quality results!

In conclusion ,computerized telescopes provide a variety of benefits both practical & cost effective wise . From being able precise pinpoint targets effortlessly ,to taking breathtaking photos distant corners universe . Even if user isn’t professional astronomer they can still enjoy great experience using automated scope .

Aperture and Magnification

Aperture is a fundamental component of any optical device, and it’s defined as the size of the opening through which light passes. A bigger aperture allows more light to enter and increases image brightness, while a smaller one reduces image brightness but provides greater depth of field. In photography and videography, having control over your aperture setting can make all the difference in creating beautiful images. It affects both exposure (how much light enters) and depth-of-field (how much background blur you get).
The most common way to control an aperture is with diaphragm blades that stop down or open up depending on how you set them. The wider the blade opening, the larger your lens’s maximum aperture will be; likewise, if you close them down more then your maximum available aperture will decrease too. This gives you full control over not only how bright an image appears but also its level of detail in both foreground and background elements.

Magnification is another important factor when considering optics – it determines how large an object appears when viewed through a lens or microscope compared to its actual size without being seen through magnifying glass at all. Magnified objects appear closer than they really are due to increased apparent size/distance ratio caused by lenses bending light rays into new paths relative to their original direction before entering the lens system. Magnification usually refers to linear magnification – doubling an object’s width would result in twice as much magnification compared with its height increasing twofold instead! The higher number indicates greater amount of enlargement which means that details can be better observed when looking at things under high levels of magnification power provided by certain optical devices like microscopes binoculars etcetera .


Telescope mounts are an essential part of any astronomer’s toolkit. They provide a stable platform for the telescope to be mounted on, allowing the astronomer to observe and photograph celestial objects with ease. A good telescope mount should be able to hold its position accurately while tracking the stars as they move across the night sky. The most common type of mount is an equatorial mount, which uses two axes that rotate around two perpendicular axes in order to track the movement of stars across the sky.

There are several different types of telescope mounts available, each with their own advantages and disadvantages. Altazimuth mounts are simple in design but can only track objects in one direction at a time. German equatorial mounts offer more flexibility but require precise alignment before use due to their complexity. Dobsonian mounts offer excellent stability and portability, making them ideal for amateur astronomers who don’t have access to large observatories or extensive observing platforms.

Finally, there are computerized GoTo telescope mounts that automatically locate visible celestial objects using motors connected to onboard computers or hand-held controllers. These allow astronomers to quickly find and observe many different kinds of astronomical events such as comets or supernovae without having to manually slewing their telescopes around all night long! Computerized GoTo systems also allow users to save settings so they can easily return back again if they need another look at something they’ve already observed earlier on during their session – perfect for anyone wanting quick access when it comes time take photos or video sequences!

Eye Pieces, Barlow Lenses, and Filters

Eye Pieces
The eye piece is the most important part of a telescope. It’s what you look through to view distant objects, and it determines the magnification level of your image. Eye pieces come in many different sizes and shapes, and can be chosen based on personal preference or viewing requirements. A good quality eye piece will give you excellent clarity, contrast, and sharpness when viewing celestial bodies like planets and galaxies; however, cheaper models may provide a distorted or blurry image that isn’t suitable for visual astronomy. Additionally, some eye pieces have special features such as adjustable eyecups for comfortable long-term use or multi-element designs that increase contrast by reducing chromatic aberration from high magnifications.

Barlow Lenses
A Barlow lens is an auxiliary optical device used with telescopes to increase the effective focal length (magnification) of any given eyepiece lens system without needing to physically change out the eye piece itself. This allows astronomers to use one set of optics with multiple magnification levels without having to purchase additional lenses. Barlows typically contain two elements – either glass lenses or mirrors – which are placed between the objective lens (or primary mirror) at the base of a telescope tube and its associated eyepiece lens system above it. The optical design of these devices causes light rays entering them from below to become focused more tightly than they would have been otherwise; thus increasing their overall magnification power significantly over what was originally intended by simply using an eye piece alone.

Telescope filters are also essential components in astronomical observations since they allow observers to reduce glare from bright stars while still allowing faint objects nearby within same field-of-view remain visible enough for detailed study purposes due largely in part due their ability block certain wavelengths of light passing through them as dictated by specific filter type being utilized at time observation process begins taking place.. Generally speaking there four main types astrofilters available: Lumicon UHC/LPR Nebula Filters—which help reveal nebulous structures better than ever before possible prior introduction new technology into hobbyist market—Solar Optical Neutral Density Filter systems designed specifically safeguarding human eyesight during solar observation sessions occurring outdoors environment., Moon Filters providing enhanced views lunar surface detail while still managing maintain brightness levels safe observing ranges even during times full moons present sky overhead., And finally Light Pollution Reduction Filters – also known “LP” filters acronym — serving purpose cutting down unwanted artificial lighting sources found cities towns modern world order so make deep sky object tracking easier less taxing engaging activity night skies no longer offer quite same level darkness once did years ago past now gone forever…
