Here is an nice Sharpless object for all size imaging systems. Sh2-53 is the group of small bright nebula in the center that a larger telescope can easily uncover more detail and structure. The wide field setups will pick up the surrounding Sharpless objects, Sh2-48 is the small one at the bottom and part of SH2-49 can be seen. Sh2-49 is better known as Messier 16. The hydrogen alpha filter works very nice for a good high contrast image.

Sharpless notes that Sh 2-53 consists of "About six detached portions". The area is prominent at both radio and infrared frequencies.

Avedisova places the nebula in the complex star formation region SFR 18.18-0.30, which includes 4 molecular clouds, a methanol maser and at least 4 additional HII regions visible at radio and infrared frequencies.
