The Crescent and Soap Bubble Nebula Size:42cm x 59cm, 16.5inches x 23.4inches but much more exposure wasThe crescent and soap bubble are classic objects in deep sky Astro. The crescent is a wolf rayet nebula, and in this image I sought to emphasize its faint Oiii shells. The soap bubble nebula is one of the first amateur nebula discoveries, and so it remains a popular object of note for amateur images. I captured this image with over 100 hours of exposure time using my triple telescope system here in texas!
