What to Consider When Choosing the Best Astro A20 Wireless

The best space telescopes arent just any old telescope. Theyre equipped with special features that make them easier to use, like built-in laser guides that help with aimpoint identification and tracking, or digital cameras that can be attached for closeup images.

One of the most important features to consider when buying a new telescope is whether it is hand-held or mounted. Mounted telescopes are attached to an equatorial mount via a set of screws, which allows them to track and rotate around the celestial body they’re observing.

Hand-held telescopes typically have two parts: a tube that houses the optics and a base that connects to a tripod or a bench for stability. These tubes often fold up into a compact shape that makes them easier to store and transport. However, their smaller size makes them more difficult to use for long periods of time.

The following sections contain some of the key features to look for when choosing the best space telescope for your needs.

Telescope Type

There are several different types of telescopes you can choose from including refractors, reflectors, catadioptics, and wide field imagers.

  • Refractors are classic telescopes that use lenses to bend light before it reaches the eye. This allows the user to see objects at a greater distance than would otherwise be possible.
  • Reflectors do the opposite, using mirrors instead of lenses to reflect rather than bend light. This results in less distortion but shorter focal lengths compared to refractors.
  • Catadioptics is a hybrid design that uses elements of both refractors and reflectors. It uses multiple lenses or mirrors to create a magnified image, but without the bulkier equipment required for a refractor.
  • Wide field imagers take photos or video frames that display a large portion of the sky at once. This type of telescope may include a camera or a sensor that creates its own image by processing the light gathered from many individual pixels.

Mount Type

Mounts come in a variety of shapes and sizes, but the majority of them are equatorial, which means they can be rotated to track a moving object such as a satellite.

Telescopes on equatorial mounts are often heavier due to the additional material required for the mounting hardware. Lightweight equatorial mounts are available, but they tend to be more expensive.

Another style of mount is the altazimuthal mount, which is also known as a gimbal mount. This type of mount can move in any direction but is usually limited to a single plane.

Weight

A lightweight space telescope will be easier to use over the course of an entire observing session. The added convenience of having a lightweight telescope helps with precision aiming, allowing the user to keep their eyes on the target rather than searching for the tip of the nose. Telescopes with metal alloys will be heavier, while polycarbonate will result in a lighter weight.

Also, keep in mind that a heavy telescope can become unbalanced, leading to difficulty maintaining focus. If the weight difference is significant, look for a telescope with counterweights to even out the device.

Size and Power

The larger the telescope, the larger the image produced. While this may seem obvious, there are plenty of small telescopes out there, and the largest ones can sometimes be pretty hefty. Its important to consider how much room you have to store and use the telescope.

Power is another factor to consider. Lightweight telescopes may lack power, while larger models can pack a wallop. Again, its important to think about where you plan to store the telescope and how frequently you’ll need to use it.

Focal Length

The focal length of a telescope refers to the distance between the lens or mirror surfaces that form the optical image. Focal length can vary based on the type of telescope, so be sure to check what the specific product offers.

For example, a typical refractor will have a longer focal length than a wide field imager. Longer focal lengths mean the ability to see dimmer and farther targets.

Focal length can also affect the size of the image produced. A longer focal length will result in a wider image, which can be helpful for seeing details in large targets. Wider images can also reduce the amount of detail lost due to diffraction, which occurs when the edges of the image begin to blur due to the wavelength of light.

Field of View

The field of view (FOV) of a telescope refers to the area of the sky that a single frame of the telescope can encompass. In other words, it is the diameter of the circle that the device can see at once.

For instance, a 6-inch telescope will have a broader FOV than a 4-inch scope. Keep in mind that a wider FOV requires a longer exposure time, which could mean missing a potential observation because the shutter wont open.

Also, keep in mind that not all space telescopes offer a full FOV. Some may have a narrower angle of view, which can limit the areas that the user can explore.

Optical Quality

The quality of a telescope refers to the clarity of its optics and the absence of aberration, which are minor deviations from perfect alignment. Aberrations can negatively impact the sharpness of vision.

Difficulties focusing due to poor optics can be frustrating, especially if its only a slight adjustment that would correct the issue. Maintaining focus is one of the more tedious aspects of good telescope maintenance, so opt for a scope with clear optics that will help you get the most out of your viewing experience.

Image Quality

The resolution of a telescope refers to the number of pixels used to create an image, which can range dramatically depending on the scope. For instance, a high-end digital camera might have a resolution of 576p, which stands for pixels horizontally by pixels vertically. A scope with a higher resolution will produce a more detailed image.

However, the size of the pixel does not indicate the quality of the image. Factors like the quality of the lens, the brightness of the stars, and the presence of atmospheric distortion can all play a role in the quality of the image produced.
