Celestron 10mm and 20mm basic eyepiece overview by Northern Optics

While here check out our website https://bit.ly/3htFtlS 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.
