      Description

      I was eyeing off this target as one of the main nebulas I want to image for the 2021 milky way season but was delayed by over a month due to the unrelenting wet weather. However, in early August was finally able to get started on the data acquisition phase. Of the three narrowband filters, H-alpha had by far the strongest signal. [OIII] was surprisingly weak so tried not to stretch it too far. [SII] was pleasantly strong (yellow regions). Probably my favorite Hubble palette image so far that I've pulled together.
