Aquarius

Water Jar

Aquarius water jar

common observer pattern · high confidence

A small Y-shaped jar near the celestial equator marks the water-bearer's stream. It is subtle but satisfying once the bright summer stars have moved west.

Central RA: 22^h 26^m 07.9^s
Central Dec: −01° 19′ 30″
Brightest member: V 3.84
Best months from 50°N: September–December evenings
Suggested instrument: naked-eye
Approx. span: 9.4°

Finder context

This wider chart is deliberately schematic: it uses nearby bright-star context and boxes the asterism’s member-star footprint, but it does not draw official constellation boundaries or promise horizon/season precision.

Framing: Approximate member-star span: 9.4°; use at least 13.2° field for context.

Observing and imaging

Naked eye

Primary naked-eye pattern; suburban skies should show the main stars unless the description notes a low horizon or dark-sky need.

Binoculars

Binoculars are optional: use them to check colours, nearby doubles, or richer Milky Way background.

Small scope

A telescope is usually too narrow for the whole shape; use it after the pattern has guided you to a target.

Imaging

Frame as a wide-field scene in/near Aquarius; a field of view around 13° keeps context without claiming exact constellation boundaries.

Observability from your latitude

Uses this asterism’s centroid RA/Dec: transit altitude, hours above 20°, and a month-scale evening window. Default is Edmonton-ish 50°N.

Naked-eye visibility by sky class

Approximate limiting magnitudes: Bortle 3 ≈ V 6.6, Bortle 5 ≈ V 5.6, Bortle 7 ≈ V 4.6. The shape is counted recognisable when at least 70% of defining stars clear the limit.
