If you love deep sky astrophotography or galaxy hunting, Markarian’s Chain is a target you must not miss. Located in the Virgo Cluster, this striking chain of galaxies stretches across the spring sky. It offers a breathtaking view of interacting galaxies, elliptical giants, and spirals — all in one frame.
In this blog, we explore what Markarian’s Chain is, how to observe or photograph it, and why it fascinates astronomers worldwide.
What Is Markarian’s Chain?
Markarian’s Chain is a visually stunning line of galaxies located in the heart of the Virgo Cluster, around 50–60 million light-years away. It is named after Armenian astrophysicist Beniamin Markarian, who studied their shared motion.
The chain includes several famous members:
- M84 (NGC 4374) — a massive elliptical galaxy
- M86 (NGC 4406) — another giant elliptical
- NGC 4435 & NGC 4438 — a pair of interacting galaxies called “The Eyes”
- NGC 4458, NGC 4461, NGC 4473, NGC 4477 — completing the visual chain
What makes this chain so fascinating is its visual alignment. The galaxies appear strung together like pearls, though they are part of the larger Virgo Cluster, which holds over a thousand galaxies.
How to Observe Markarian’s Chain
The best time to observe Markarian’s Chain is from March to May. During this period, Virgo rises high in the evening sky. While it’s best seen from the Northern Hemisphere under dark skies, southern observers can still spot it, though lower on the horizon.
For equipment, you have several options:
- With small telescopes (4–6 inch), you will spot M84 and M86 as bright ellipses.
- With larger telescopes (8–12 inch), you can see the fainter NGC galaxies and finer details.
- For astrophotographers, a camera setup with a short focal length (300–600 mm) can frame the entire chain beautifully. Longer focal lengths allow for close-up views of individual galaxies.
Using a star chart or planetarium app is highly recommended. It will help you navigate the dense, galaxy-rich Virgo region.
Astrophotography Tips for Markarian’s Chain
Photographing Markarian’s Chain is both rewarding and challenging. But with the right approach, you can create a stunning image.
✅ Choose the right focal length. The chain spans about 1.5 degrees. A focal length between 300 mm and 700 mm works well on APS-C or full-frame sensors.
✅ Collect long exposures. Aim for 3–6 hours of total integration time. This helps reveal faint details, especially when using luminance or RGB filters.
✅ Process with care. Stretch the faint outer features while preserving the bright galaxy cores. This brings out the subtle interactions and color contrasts.
✅ Consider mosaics. Want to capture more of the Virgo Cluster? Plan a multi-panel mosaic to expand your field.
Why Is Markarian’s Chain Important?
Markarian’s Chain is more than just beautiful. It tells a deeper cosmic story. As part of the Virgo Cluster — one of the nearest and most massive clusters to the Milky Way — it helps astronomers study:
- Galaxy evolution in crowded environments
- Gravitational interactions and mergers
- The universe’s large-scale structure
For amateur astronomers, the chain is a reminder of the universe’s dynamic nature. Even small backyard telescopes can reveal incredible cosmic wonders.
Conclusion
Markarian’s Chain is a jewel of the spring sky. Whether observing or photographing, it offers both scientific intrigue and visual beauty.
