10mm Vs 20mm Telescope Lens. The scope’s highest useful magnification is 307x and the lowest is roughly 19x. To determine the focal lengths of eyepieces that fall within the magnification limits,.
Telescopes come in a variety of sizes and with different lenses. Two of the most popular lenses are the 10mm and the 20mm. Understanding the difference between these two lenses can help you decide which one you need for your telescope.

The 10mm lens is a wide-angle lens and it offers a wider field of view than the 20mm lens. This lens can be used to view larger objects, such as galaxies and star clusters. It is also well-suited for observations of the Moon, planets and other celestial objects.
The 20mm lens is a narrow-angle lens and it offers a narrower field of view than the 10mm lens. This lens is generally used for higher magnification and for viewing smaller objects, such as double stars and planetary detail. It is also well-suited for observing faint objects, such as galaxies and nebulae.
When it comes to choosing between the 10mm and the 20mm lens, it is important to consider what you will be observing. If you are looking for a wide field of view, then the 10mm lens is the better choice. If you are looking for higher magnification and a narrow field of view, then the 20mm lens is the better choice.
In terms of cost, the 10mm lens is generally more affordable than the 20mm lens. However, keep in mind that the 20mm lens will provide more detail and better images. It is also important to consider the quality of the lenses when making your decision.
When using your telescope, it is important to remember that the 10mm and 20mm lenses are not interchangeable. They are designed to work with specific telescopes and cannot be used with other telescopes. It is also important to remember that the quality of the lens can make a big difference in the quality of your images.
In conclusion, the 10mm and 20mm lenses have different characteristics and are designed for different purposes. It is important to consider what you will be observing and the quality of the lenses when making your decision. With the right telescope and the right lens, you can get amazing views of the night sky.
Celestron 10mm and 20mm basic eyepiece overview by Northern Optics
Of a similar optical design to the Skywatcher modified achromatic designs and perfect for starter telescopes. Much better build and optical quality than some other unbranded budget eyepieces. Both have their own attributes. The 10mm gives a little more magnification. The 20mm gives a wider view with good contast. It does however have an internal body wall that is a little polished, causing some reflection on light. Thank you for…
Basically the 10mm gives twice the magnification of the 20mm.The 10mm is best used for looking at the moon and planets. The 20mm is best used for star. The “mm” refers to the measurement of the lenses, taken in milli-meters. Different size lenses will provide different levels of magnification, with a lower “mm” providing more. , 10mm Vs 20mm Telescope Lens.
