Sh2 158 Nebula on 2025-10-14,15,16,17,18

Sh2 158, also known as NGC 7538 and the Northern Lagoon Nebula, is an active star-forming emission nebula located in the constellation Cepheus about 9,100 light-years away. It hosts one of the largest known protostars, a massive young star approximately 300 times the size of our solar system. The region is home to numerous young, massive stars and is part of a larger star formation region within the Milky Way's Perseus Arm (Note the clouds of scattered gas and dust throughout this picture). Another object, Sh2 159, dark-red, is located below and to the left of Sh2 158. This photo was taken in Kyle, Texas through a 6-inch f/4 Telescope, on a ZWO AM5 mount, with a ZWO ASI533MC PRO color camera plus a dual-band Ha-O III filter. The processing was done in PixInsight. The total image acquisition time is: 20 hours 20 minutes 00 Seconds.
