Brightest Galaxies

While many people start with the Messier list, the "Brightest Galaxies" database (often referred to in amateur circles as the "Brightest 200") is the definitive roadmap for those who want to see the true "heavyweights" of the local universe.

Rather than being a historical accidental discovery like Messier’s work, this database is a filtered "power list" of the most spectacular island universes visible from Earth, regardless of which catalog they originated in.

History & Who Made It

The list of the 200 Brightest Galaxies wasn't the work of a single 18th-century astronomer. Instead, it was a collaborative project of the Royal Astronomical Society of Canada (RASC) and the Astronomical League in the 1980s and 1990s.

They took the massive New General Catalogue (NGC) and the Index Catalogue (IC)—which contain over 13,000 entries—and applied a strict "brightness filter." By selecting galaxies with an integrated magnitude of 11.5 or brighter, they created a database that is accessible to anyone with a 6-inch to 8-inch telescope, even under moderately light-polluted skies.

The Purpose: Mastering Galaxy Morphology

The primary purpose of this database is to move the observer beyond just "finding" an object and into "understanding" it.

• Morphological Training: Because these galaxies are the brightest, they are the only ones where an amateur can clearly distinguish between different shapes (Spiral, Elliptical, and Irregular).

• Equipment Benchmarking: This list is often used to test telescope optics. If an observer can see the "dust lane" in a galaxy from this list, they know their equipment is perfectly collimated.

• The "Step Beyond": It serves as the final gateway before an observer dives into the thousands of much fainter, more obscure galaxies that require 12-inch+ "light bucket" telescopes.

What Objects Can Be Found In It?

The database is a survey of the varied "species" of galaxies found in our local supercluster. While they are all "galaxies," the visual experience of each category is very different.

The Database Breakdown

Catalog Name: 200 Brightest Galaxies Creators: Compiled by RASC and The Astronomical League Filter Criteria: Integrated Magnitude < 11.5 Total Objects: 200

Category: Approximate Count

• • Spiral Galaxies (S/SB): 142 (These show "arms," "bars," or "dust lanes" under dark skies.)

  • Elliptical Galaxies (E): 35 (Smooth, ball-like concentrations of old stars; often the brightest in galaxy clusters.)
