    Description

    The Cave Nebula in Cepheus is one of those wonderful sky marvels, where emission and reflection nebulas mix and form a colorful star nursery. The stellar wind of newborn hot stars sweep a shockwave through the interstellar gas and dust, leading to even more star birth.

    Along with the LRGBHa version there is the Ha picture with stars removed, you may blink and enjoy the different vistas.

    LRGBHa: 27+5+7+12+41 x 8min subframes at -20°c, Gain zero for max. dynamic range.
