The owl cluster in Cassiopia has the appearance of a bird in flight – at least one magazine editor.

The world is flowing with the deep-sky objects named Crazily. However, I am guilty of such a naming many years ago Astronomy And Deep sky Magazines – Owl Cluster, NGC 457, in Cassiopia.
This object was discovered by William Herschelle on August 18, 1780. When I first saw this cluster with my selesteron 8, I immediately saw that two major “eyes” looked and who appeared as a separate body of stars, with legs, and “feathers” of bright stars.
So I immediately started calling it an owl cluster, which was caught. The Shopis object is about 8,000 light-year away and is about 21 million years old. It consists of about 150 stars.
The field has two brightest stars, FI Cassiopia (which shine at magnitude 5.1) and HD 7902, at magnitude 7.0, “eyes”. This cluster also includes some good red stars, including the Variable Super Zant V466 CAS.
Overall, this great group of young stars shines in 6.4 to magnitude and 13 ′. I hope you enjoy watching it, and perhaps you will also be involved in seeing an owl.
