Blue reflection nebula in Orion. Surrounded by faint dust needing long integration.

Large emission complex. Frame the head for best detail. Strong Ha.

Extremely faint blue reflection near Rigel. Needs dark skies and lots of data. Very challenging from Bortle 5.

Very faint ancient PN. Strong OIII. Needs serious integration. Rewarding challenge.

Large Ha/OIII target. Setting by midnight in March — prioritise early evening.

Strong Ha emission. Getting low by late March.

Faint SNR with beautiful Ha/OIII filaments. Needs lots of integration.

Mixed emission + reflection. Fox Fur Nebula benefits from Triband blue boost.

Compact WR bubble. Very low by late March — image ASAP. Strong OIII.

Classic pair. M82 has strong Ha starburst core — Triband captures this plus broadband structure. Circumpolar.

NGC 3628 has faint tidal tail. Best when Leo is highest.

Unusual PN + galaxy pairing. Triband captures OIII-rich Owl and the galaxy.

Ha regions in Whale disc visible with Triband. Frame landscape.

Active Seyfert nucleus with anomalous arms visible in Ha. Underrated target.

Face-on spiral + companion NGC 5195. Ha regions in arms visible with Triband. Iconic.

Beautiful flocculent arms with subtle Ha patches. Needs good integration.

Large face-on spiral with prominent HII regions. Low surface brightness — needs lots of data.

M84, M86, NGC 4438 (Eyes). Low from Worthing but stunning composition.

Iconic dust lane. Very low altitude (~25°) from 50.8°N.

Perfect edge-on with prominent dust lane. Higher altitude than Sombrero.

Distinctive dark dust band. Relatively bright — good for shorter sessions.

Bright compact galaxy with distinctive starburst ring. Good for shorter sessions.

Point near M87 to capture dozens of galaxies in one frame.

The showpiece glob. Short subs, lower gain to resolve individual stars.

Rich and resolved. Quick win target.

Tiny but bright. Strong OIII ring. Drizzle to enlarge. Quick win.

Gorgeous Ha/OIII two-tone structure. Duo-Band shows this beautifully.

Bright compact PN. HDR blend short + long subs. Strong OIII. Circumpolar.

Frame the Cygnus Wall for best detail. Strong Ha. Works in short summer nights.

Dense ionisation front is spectacular. Frame the 'neck' region.

Stunning filaments. Ha AND OIII — Duo-Band shows both. One of the best targets in the sky.

Western arc with 52 Cygni. Pickering's Triangle between arcs is another panel.

WR bubble. OIII shell + Ha interior. Layered structure.

Huge emission complex around Gamma Cygni. Rich Ha.

Near Cygnus X-1 (black hole). Strong Ha. Less photographed.

Pillars of Creation. Low from Worthing (~20°) but bright.

Extremely bright. Very low from Worthing (~15°).

Mixed emission/reflection. Triband captures both. Very low altitude from Worthing.

Very bright but extremely low (~12°) from Worthing.

Frame the trunk for best results. Full nebula needs mosaic. Strong Ha.

Blue reflection nebula surrounded by dust. Triband blue boost helps enormously.

Emission core, reflection wings, plus dark Barnard 168 dust trail. Triband ideal.

Wind-blown bubble. Strong Ha + OIII. Frame with nearby M52.

Compact emission around open cluster. Strong Ha.

Faint but fascinating. Part of the Cepheus molecular cloud.

Prominent HII regions and frequent supernovae. Circumpolar.

Fine spiral + iconic compact group. Deep integration for Quintet.

Nearest major galaxy. Core + M32/M110 frame well. Ha regions in arms with Triband. Iconic.

Large spiral with massive HII regions (NGC 604). One of the best Triband targets.

Large bright emission. Melotte 15 at centre makes a great crop. Circumpolar.

Adjacent to Heart. Image both across sessions. Strong Ha. Circumpolar.

Compact emission with Bok globules. Good OIII. Circumpolar.

Iconic cluster pair. Triband preserves star colours. Short subs. Quick target.

Pillar structures like Eagle Nebula. Strong Ha. Underrated.

Stunning edge-on with prominent dust lane. M31 analogue.

Nearest large PN. Very low from Worthing (~18° max). Only on clear southern nights.

Illuminated by Gamma Cas. IC 63 = Ha, IC 59 = reflection. Triband captures both.

Enormous ancient SNR. Extremely faint Ha filaments. Multi-night project. Ultimate bragging rights.

Beautiful OIII-dominant WR bubble. Very low from Worthing. Duo-Band essential.
