Sh2-148 is an emission nebula in the constellation Cepheus, positioned approximately 18,900 light-years from Earth. This compact HII region is powered by embedded massive OB stars ionizing the surrounding hydrogen. It reaches culmination at astronomical midnight in early September, marking the optimal window for narrowband imaging.

My first attempt with the Foraxx palette on the North America Nebula (C 20). Three nights in July 2026, 6 h 15 min of narrowband data from Koblenz.

Ha, OIII and SII blended into those coppery Foraxx tones. I love how the emission structures pop.
