Description

NGC 7139 is a planetary nebula in Cepheus. At an overall magnitude of 13.3, it spans 77 arcseconds and has a central star of 18th magnitude.

This image is comprised of very short subs (60s for L, G, and B; 75 seconds for R) binned 2x2. I kept the subs short to avoid overexposing the stars.
