The Lunar and planetary performance with AstroMaster 90AZ is great. Jupiter’s storm clouds and The Great Red Spot are easily visible, including the 4 Galilean Moon’s. Rings of Saturn are easily distinguishable from the planet, and with a high-quality eyepiece, you can get some detail on Mars.
The Moon looks spectacular with this telescope. For this price, there is no other model that can provide a better view of the Moon. The mountain ranges and craters look gorgeous, with little color defects.
You might get some idea about this telescopes’ capabilities from this video. Keep in mind the real image would look vastly better.
