NGC 2775 is a small, tightly wound spiral galaxy with a bright central core surrounded by a gossamer outer veil. A complex spiral pattern emerges in the outer veil in high resolution images, but here it appears only as a soft golden glow with just a hint of spiral structure. Visually, the core appears as a soft, out of focus star similar to a small planetary nebula.
NGC 2775 is currently well placed in the eastern sky during the early evening. (Photo credit: John Graham, 2-12-2023)
