    Default Asterisms Near the Omega Nebula



    Here's a sketch of a few asterisms I found above and below the Omega nebula. They're shown closer to the nebula than they are. I can't find a name for these star patterns. If anyone recognizes them and can name them, that'd be great. I call the bottom one the Arrowhead and the top the Trident or the Double Star Asterism. The top one has 3 bright stars at the head that kind of form a trident shape. Each star in it seems to have a mate. Anyone recognize these patterns? They're really close to the Omega nebula.

    If you are unable to find an official asterism designation for them then you could name them yourself!

    I am not sure that asterisms are official, so there are many lists.
    You could even start your own.

    Hi Joe, great sketch. Check out the Astronomical Leagues website...they have some asterisms listed. Here’s the link for you. Good hunting. And keep on sketching. Clear skies.

    Hi Joe. A very nice sketch from you. Follow up with Susan's advice on checking with the Astronomical Leagues catalogue to confirm. Thanks for sharing your nice work with us Joe, and keep them coming.

    Thank folks! I'll check out the link. I just took notice of these patterns, as they really stand out when you come across them. Much better than in my sketch. I figured someone would have named them but maybe not. By the way, I was beginning my search for the Wild Duck Cluster when I stopped and decided to sketch these stars. I found the cluster and thought it was spectacular, in a subtle way.

    Joe. When I get home I will check my resources for you. I have access to a listing of over 1100 asterisms, most of which don't have nicknames. While asterisms are not "officially" recognized, they certainly are one category of DSO that can be fun to hunt down and observe. They can range in size from quite small to quite large, and have been found both visually and via imagery. I will let you know what I find out.

    Ok, I checked my sources and there are no documented asterisms encompassing the stars you are indicating. However, I would point out that these stars are part of the open cluster associated with M17. Both objects carry the designation of NGC 6618, and are considered a cluster associated with nebulosity. In this case those stars are not good candidates for being designated an asterism since they belong to a known cluster. But they certainly do add nicely to the overall view of the field.

    Thanks KT! I don't have M17 or even M18 I think is nearby, on my list of Messier objects. I'll study M17 and NGC 6618 so I can add them to my list. Wait a minute. I DO have M17, lol! The Omega Nebula is one of my favorites!

    I agree Joe, Messier 17 is a fine object, particularly from a darker location. Personally I am more fond of its other nickname, the Swan Nebula, as I find it particularly appropriate for the shape I see. NGC 6618 is the same object, being its designation within the New General Catalogue for the cluster/nebula combination. Enjoy the views.
