Recommended Targets
Ranked by tonight score, moon impact, and target type.
North America Nebula
35
Emission nebula
Cygnus
23:00 - 01:00
Combine with the Pelican for a dramatic Cygnus coastline. Peaks near 00:00 at roughly 78 deg altitude.
Strategy: Good moonlit choice with narrowband filters.
Gear: Wide-field optics with narrowband filters
Crescent Nebula
35
Emission nebula
Cygnus
22:00 - 00:00
Wolf-Rayet stellar winds carve the luminous bubble. Peaks near 23:00 at roughly 72 deg altitude.
Strategy: Good moonlit choice with narrowband filters.
Gear: Fast optics with narrowband filters
Heart Nebula
35
Emission nebula
Cassiopeia
02:00 - 03:00
Pair with the Soul Nebula for a sweeping Cassiopeia mosaic. Peaks near 03:00 at roughly 72 deg altitude.
Strategy: Good moonlit choice with narrowband filters.
Gear: Fast optics with dual-narrowband filters
Soul Nebula
35
Emission nebula
Cassiopeia
02:00 - 03:00
A favourite wide-field partner to the Heart Nebula. Peaks near 03:00 at roughly 70 deg altitude.
Strategy: Good moonlit choice with narrowband filters.
Gear: Fast optics with dual-narrowband filters
Hercules Globular Cluster
25
Globular cluster
Hercules
21:00 - 22:00
A summer globular bursting with faint blue stragglers. Peaks near 21:00 at roughly 65 deg altitude.
Strategy: Forgiving target for imperfect transparency.
Gear: Medium aperture scope to resolve the core
Andromeda Galaxy
7
Spiral galaxy
Andromeda
02:00 - 03:00
Sweep up the satellite galaxies M32 and M110 in wide-field frames. Peaks near 03:00 at roughly 75 deg altitude.
Strategy: Moon-sensitive. Wait for darker hours or save for another night.
Gear: Short focal length scope and dark skies
Moon Strategy
Waning Gibbous
Very bright moon. Treat this as a narrowband, lunar, planetary, calibration, or equipment-tuning night.
Session Checklist
- Confirm cloud breaks 60 minutes before travel.
- Pre-cool optics and pack dew control.
- Sync mount, polar align, and run a short test exposure.
- Have a short lunar, planetary, or calibration fallback plan.
- Prioritise narrowband or bright clusters while the moon is high.
