I need help, I don't know why there is a little blue area on the shape. this bluish thing seems to appear on all the other shapes on this image, is it the telescope? or something else.
also is this a star or a galaxy?.

Hi FawziOmar and welcome to the Zoo
All the objects in this image are stars from our galaxy, but something went wrong with the imaging/filters. The colours are not real and the blue dots are also artifacts.
happy hunting ! 😄
