When the moon is bright, as it was last night, I focus on imaging the brighter narrowband objects. A few days ago, I imaged the fainter, Western Veil and Pickering's Triangle. Last night, I imaged the Eastern Veil, and managed around 100 minutes of integration with the RASA 8 and DS10C (NBZ filter) before the clouds moved in.
The Veil is a supernova remnant created by a star if about 20 solar masses some 10,000 years ago. William Herschel discovered the nebula on Sept. 5, 1784 and described it as streams of branching nebulosity. Our modern cameras can tease out the remarkable complexity of this nebula. NGC 6992 is particularly complex and it sometimes called the "Network Nebula." The captured images show this wonderful complexity, especially the first image, which is a close, starless crop of the original image capture.
