If you interested in learning more about the night sky and planetary imaging, then you may be looking for Optical telescopes or scopes. In this article, we will talk about some of the popular types of portable telescopes and scopes, including the ones you can use with your phone.
Optical Telescopes
The design specifications of a telescope refer to the optical performance and characteristics of the telescope. The specifications of a telescope are determined by its focal length and the number of lenses used to make it. The focal length the length of the objective divided by the diameter of the tube that focuses light. This factor controls the field of view and the scale of the image at the focal plane.
Maximum Magnification
The maximum magnification achievable by a telescope generally about 3.5x. However, there is a limit to the brightness of the image that achieved by decreasing the magnification. The exit pupil, or cylinder of light that exits the eyepiece, must match the diameter of the telescope’s aperture. Increasing the magnification past this limit will result in wasted light.
Many different Sizes And Shapes
Optical telescopes come in many different sizes and shapes. There are three main classes of telescopes: refractors, reflectors, and catadioptrics. Each class has its own advantages and disadvantages, but all of them feature professional optics.
Optical Scopes
Whether you’re a beginner or an expert, it’s important to have good optics on a portable telescope. There are two major types of telescope: Newtonian reflectors and catadioptrics. A Newtonian reflector has a concave primary mirror and a flat secondary mirror. They combine both optical elements to create a sharp image. The biggest advantage of a Newtonian reflector is its affordability. This type of telescope will allow you to observe a lot more, for a lower price.
Focal Length
The distance from the main lens to the image called the focal length. A 10-inch telescope will gather thirteen times more light than a 2.8-inch telescope. Moreover, a 10-inch telescope will give you more detail than a two-inch scope. The longer the focal length, the less light will be wasted, so you can see more detail.
RVO Horizon 72ED
One such telescope the RVO Horizon 72ED. The telescopic tube is only 34cm long when it collapsed and weighs only 2.68kg. It also has a dew shield that can be easily removed. The telescope sold with a separate imaging kit, the PS947, which contains a 1.0x rotatable field flattener and finder/guidescope.
Optical Scopes for Planetary Imaging
Professional optics are essential in planetary imaging. High-power telescopes generally designed with large-sized eyepieces that are large enough to allow for wide-field viewing. Eyepieces with large focal lengths are generally f/10 or f/15 and work well for viewing planetary objects at high magnifications. However, their wide-field capabilities limited.
Aperture
The diameter of the telescope’s outermost lens or primary mirror is called the aperture. This is where light enters the telescope. A larger aperture allows more light in, increasing clarity and brightness. This is critical when viewing deep celestial objects, as light from deep space is much fainter.
Vixen Optics
The Vixen Optics 25092DS SXP Mount is among the best telescopes available on the market today. It delivers pinpoint images with virtually no false color. Its high-definition LCD screen is equipped with a cutting-edge hand-held controller that helps you navigate and control the telescope while imaging. The high-definition SD lens and SD glass help produce clear and sharp images.
Observing the Night Sky with a Phone Adapter
Optical scopes for observing the sky available in a variety of sizes and features. You can use them to see the moon and other celestial objects. They also allow you to zoom in to take pictures of objects in the night sky, though the quality will be reduced. You can even use your smartphone to take pictures of the night sky – as long as you have an adapter for your smartphone.
Offer a large field of View
Spotting scopes are a more portable and affordable alternative to telescopes. They offer a large field of view, which is useful when star-hopping. Furthermore, they are lighter than telescopes and can be used while hiking or camping. Also, they are easier to stabilize.
DS-70 DSLR Camera
The DS-70 DSLR camera scope weighs only 2.3 pounds and is portable. It can observe up to 500 yards and can be used with various astronomical eyepieces. However, it is not as sharp as a more expensive model. However, it comes with a carrying case and a small tripod.
