I took direction from Huey’s Observing Extragalactic Objects Within Host Galaxies once again. His annotations are to HK83 data from this article: Hodge, P. W., & Kennicutt, R. C., Jr. (1983). “An Atlas of H II Regions in 125 Galaxies.” The Astronomical Journal, 88, 296–328. Using AI, I was able to get the relevant RA and Dec data to use in Pixinsight’s AnnotateImage script. It appeared to me annotating additional entries would jam up the thin, edge on galaxy. So I chose just three. The data from the csv file follows:
NAME RA DEC
HK83 7 190.63598 32.5418444
HK83 41 190.553537 32.5457778
HK83 79 190.456265 32.5426778
