    Question about an object

    I'm sorry for a very simple question. I should be able to figure this out myself, but thought somebody else will probably be able to do it very easily, so I figured I'd just ask. Could someone let me know what constellation this is in?

    22h 17m 34.0s +00 17′ 01″

    I think it might be Aquarius, but am not sure.

    It's the location of a proto-cluster called SSA22.
    As above, so below

    Yup, Aquarius. Just a little way away from Alpha Aquarii.

    There is a fun little tool here that lets you aim a virtual telescope at any point in the sky. You can see the point relative to other stars and constellation boundaries using it.

    Thanks, and thanks for the resource as well!

    Ohhhh, SSA22. Where I once used 8 half-nights on a 4-meter telescope seeking emission from carbon and oxygen in Lyman alpha blobs. Far out. (Spoiler - resonant scattering of hydrogen Lyman alpha photons may explain why the other species are so weak in some of these giant nebulae).

    Dang, you've ruined the whole story for me now.

    Cool. Im writing something about it, which has to do with Lyman alpha emissions actually.
