Edge-on disc or cigar-shaped elliptical?

  • NotThatGuy by NotThatGuy

    I've had this debate inside my head regarding a number of images. This one looked like a perfect example, so I have to ask: is this a disc viewed edge-on or a cigar-shaped elliptical? In the absence of a clear dust lane (which I don't see here), what criteria would you use to distinguish between the two?

    disk or spiral edge on for me.

    The 'points' are too sharp for it to be an elliptical.

    This galaxy also has a bulge; a bulge plus a disk is about as classically spiral as a galaxy can be, without actually having obvious spiral arms
