Refractive plastic telescope image: light comes from the object we see, and then it passes through the lens of the telescope, is concentrated on the focus, and then is shot toward the telescope eyepiece, resulting in image weightMetal focusing: According to design, focusing is simple, smooth and comfortable, with greater load bearing and more durableHigh-definition eyepieces: the main accessories for astronomical telescope observation, according to different observation targets, choose different eyepieces to achieve a better observation experienceObjective lens: 70mm large-caliber optical lens group, full-surface anti-reflection coating, the image is brighter and clearerFocusing lever: According to different usage requirements, choose to change the angle, so as to achieve better observation effect
