Recommended Targets
Ranked by tonight score, moon impact, and target type.
North America Nebula
49
Emission nebula
Cygnus
02:00 - 03:00
Combine with the Pelican for a dramatic Cygnus coastline. Peaks near 03:00 at roughly 78 deg altitude.
Strategy: Good moonlit choice with narrowband filters.
Gear: Wide-field optics with narrowband filters
Crescent Nebula
49
Emission nebula
Cygnus
01:00 - 03:00
Wolf-Rayet stellar winds carve the luminous bubble. Peaks near 02:00 at roughly 72 deg altitude.
Strategy: Good moonlit choice with narrowband filters.
Gear: Fast optics with narrowband filters
Eastern Veil Nebula
49
Supernova remnant
Cygnus
01:00 - 03:00
Filamentary shock fronts shine in OIII and Ha. Also known as Veil Nebula, Filamentary Nebula. Peaks near 02:00 at roughly 64 deg altitude.
Strategy: Good moonlit choice with narrowband filters.
Gear: Fast optics with narrowband filters
Western Veil Nebula
49
Supernova remnant
Cygnus
01:00 - 03:00
Include 52 Cygni to anchor the sweeping filaments. Also known as Veil Nebula, Filamentary Nebula. Peaks near 02:00 at roughly 64 deg altitude.
Strategy: Good moonlit choice with narrowband filters.
Gear: Fast optics with narrowband filters
Hercules Globular Cluster
39
Globular cluster
Hercules
21:00 - 23:00
A summer globular bursting with faint blue stragglers. Peaks near 22:00 at roughly 70 deg altitude.
Strategy: Forgiving target for imperfect transparency.
Gear: Medium aperture scope to resolve the core
Whirlpool Galaxy
21
Spiral galaxy
CVn
21:00 - 22:00
Tidal streams reward deep integrations. Peaks near 21:00 at roughly 71 deg altitude.
Strategy: Moon-sensitive. Wait for darker hours or save for another night.
Gear: Long focal length scope and dark skies
Moon Strategy
Moon
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.
