    Default Star Flare



    Is there a place on the forum that describes various aberrations in the eyepiece?
    I see a 4 pointed flare on bright objects. Is this normal, possibly atmospheric?

    They're called diffraction spikes, and they're caused by the four spider vanes that hold the secondary mirror in your XT8. Perfectly normal Bblamo, nothing to worry about. I personally love em. The bigger the better.

    Or using a refractor....
    As Don said Bblamo, you will also see the spikes in images taken with reflectors but not with refractors.
