OBJECT DESCRIPTION AND IMAGE SESSION

A nice pair located in the Constellation of Canis Major, close to the limit with Puppis. Both objects cover an area of roughly 13 arc minutes so they might fit in an eyepiece using moderate power. NGC 2383 is at the left and NGC 2384 at the lower right.

It was supposed these two cluster were related, however recent studies from European Scientists V. Kopchev (*), G. Petrov, (*) P. Nedialkov (**) indicate that the objects deferred considerably in their respective ages and concluded they were born in different environments.
