WebThis is normal for all Newtonian reflectors, so much so that most of us don't even notice them. They are diffraction spikes caused by the spider which supports your diagonal mirror. They are inherent in the telescope's design, and the only way to eliminate them is by going to a different design: a refractor or a Schmidt or Maksutov design.
