Svbony SV225 Mini Telescope Mount & SV225T Aluminium Tripod

SV225 MINI alt-az mount allows the telescope to move freely in two directions - altitude and azimuth. Altitude is the movement along the vertical axis and azimuth is the movement along the horizontal axis.

The advantage of an alt-az mount is that it's incredibly simple and easy to use. To move your telescope, you just turn the two knobs to adjust the altitude and azimuth angles. This makes it perfect for viewing objects in the night sky.

When buying an alt-az mount, there are several factors to consider. First, you'll want to make sure that the mount can support the weight of your telescope. Second, you'll want to look for a mount that has smooth tracking and accurate positioning for precise star gazing.
