    The Astroview 120ST eq reflector telescope produces crisp images, even at higher magnifications. Orion 120ST reflector telescope revealed the moon’s surface in stunning detail, with craters and mountains standing out clearly. The telescope is smaller than expected, but that’s not necessarily bad. Quite portable and easy to set up, it’s perfect for impromptu stargazing sessions. The 120mm aperture is deep enough, providing a good balance between portability and image quality. Midrange performance pleasantly surprised me.
