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 : http://tinyurl.com/om2adbk
And, please, always classify the object in the center of the image !
Happy hunting ! 😄
