Need help classifying.

    What's the threshold for the "edge on" classification?

    Also, I'm a bit confused as to the bulges. What is an example of a galaxy with 'no bulge'?

    Hi, this is an edgeon galaxy (with a nice dustlane):

    This is not:

    enter image description here AGZ0002wqk

    And this is just one example of a galaxy without a bulge (no visible core):

    enter image description here AGZ00024mh

    Of course, there's many more examples and it'll take a while before you're comfortable enough classifying every type of galaxy. But you're not the onlyone classifying, so it's no big deal if you make a mistake. If you're unsure you can always try a search for similar galaxies. For instance, if you want to know when a galaxy's irregular or not, search for #irregular and wathc if those results are similar to the galaxy you're classifying. There are also many helpful topics around.

    Good luck.
