This wide-field vista spans the constellations Cepheus and Cassiopeia and includes an host of deep-sky objects. From left to right: NGC 7822 (the Question Mark Nebula), LBN 576 (the Garlic Bulb Nebula), NGC 7635 (the Bubble Nebula), Sharpless 2–157 (the Lobster Claw Nebula), and Sharpless 2–155 (the Cave Nebula). The imager took 17 hours of exposure with a 2-inch scope, one-shot color camera, and Hα/OIII dual-band filter. The data were processed and presented here in an HOO palette.
