How do you classify the odd stalk like feature

    This image shows an odd stalk like feature below the main galaxy. I have classified it as irregular. Is that correct ?

    Hi mnegandhi and welcome to the Zoo

    The line at the bottom is a diffraction spike (optical artifact) caused by a bright star just outside of this image. See the zoomed out and rotated image :

    And, please, always classify the object in the center of the image !

    Happy hunting ! 😄
