M86 (NGC 4406) Observing Guide — Lenticular Galaxy in Virgo

Overview

M86 is a lenticular galaxy in Virgo, catalogued as NGC 4406. Shining at magnitude 8.9 about 60 million light-years away, it sits near M84 in the core of the Virgo Cluster and is one of the brighter members of that galaxy-rich region. Spring evenings bring it to a favorable position for advanced observers.

Lenticular galaxies occupy a morphological middle ground: they have the disk structure of a spiral galaxy but lack prominent spiral arms. M86 also has the unusual distinction of moving toward the Milky Way — one of only a few galaxies in the Virgo Cluster with a blueshift.

Basic Data

Physical Characteristics

M86 lies roughly 60 million light-years away and glows at magnitude 8.9. Its membership in the Virgo Cluster — one of the galaxy concentrations most thoroughly represented in Messier's catalog — makes it accessible through modest instruments on dark nights.

Observing Guide

Finding It

M86 lies in the Virgo region, transiting around 8–10 PM in spring. It sits just a fraction of a degree from M84, and the two make a striking pair in a low-power Eyepiece — this region is sometimes called Markarian's Chain. Locating one almost automatically puts the other in view.

Observing Tips

Galaxy observing depends heavily on dark skies and thorough dark-adaptation. Keep magnification low and resist increasing it until you've confirmed the target. M86's elliptical appearance differs subtly from neighboring M84, so comparing their shapes helps cement the identification.

Recommended Equipment

An 80mm or larger telescope is the practical minimum. On nights of good Seeing, a 100mm or more reveals the core-halo brightness gradient more clearly against the dark sky background.

Astrophotography Tips

M86 is frequently imaged alongside M84 in wide-field views of Markarian's Chain. An Equatorial mount with guided tracking, elevated ISO settings, and stacked exposures of 30 seconds to several minutes bring out both galaxies and several fainter cluster members simultaneously.

Summary

M86 in Virgo is an advanced-level galaxy target that pairs naturally with neighboring M84. Together they anchor one of the most photographically rewarding sections of the Virgo Cluster, visible each spring through a small or medium telescope under dark skies.
