  • Light pollution filter: A light pollution filter is a special filter that can be inserted into the eyepiece or the focuser to reduce the amount of light pollution and make it easier to see faint objects in the night sky.
  • Tripod or mount: A stable tripod or mount is essential for holding the telescope steady and ensuring a steady image. 
  • Power supply: Some iOptron telescopes have a built-in battery or need external power supply for the GoTo feature, consider getting an extra battery or power supply for longer observing sessions.
