🔭 February Imaging Plan — Switzerland (46°N)

Optimized for your 400 mm, 700 mm, 1000 mm, 2000 mm rigs (APS‑C, color + narrowband)

🌄 400 mm f/5 — California, Rosette, Cone Region

APS‑C FOV ≈ 3.2° × 2.1°

🎯 Best February Target: California Nebula (NGC 1499)

Why this target fits 400 mm California is huge — at 400 mm you frame the entire nebula with beautiful Hα structure.

Filters

• Narrowband Hα/OIII (duo‑band)

• RGB optional for star color

Exposure strategy

• 180–240 s NB

• 60–120 s RGB

• 8–12 h total integration

Expected result A long, glowing Hα ribbon with subtle internal texture.

Secondary February target: Rosette Nebula (NGC 2237)

🌌 700 mm f/7 — Cone / Christmas Tree & Monkey Head

APS‑C FOV ≈ 1.8° × 1.2°

🎯 Best February Target: Cone Nebula + Christmas Tree Cluster (NGC 2264)

Why this target fits 700 mm You capture the Cone pillar with excellent detail while keeping the surrounding cluster in frame.

Filters

• Narrowband Hα/OIII

• RGB optional

Exposure strategy

• 240–300 s NB

• 10–15 h total integration

Expected result A dramatic Hα pillar with rich star fields and dust structures.

Secondary February target: Monkey Head Nebula (NGC 2174)

🌠 1000 mm f/4 — Monkey Head Close‑up & Medusa

APS‑C FOV ≈ 1.2° × 0.8°

🎯 Best February Target: Monkey Head Nebula (NGC 2174) — Close‑up

Why this target fits 1000 mm At 1000 mm you resolve the internal Hα knots and dust structures beautifully.

Filters

• Narrowband Hα/OIII

• RGB optional

Exposure strategy

• 180–240 s NB

• 8–12 h total integration

Expected result A high‑contrast, detailed nebula with crisp emission structures.

Secondary February target: Medusa Nebula (Abell 21)

🌑 2000 mm f/10 — Small Planetaries in Gemini & Orion

APS‑C FOV ≈ 0.6° × 0.4°

🎯 Best February Target: Planetary Nebula NGC 2392 (Eskimo Nebula)

Why this target fits 2000 mm NGC 2392 is small and bright — perfect for long focal length and narrowband detail.

Filters

• Narrowband Hα/OIII mandatory

• RGB optional for star color

Exposure strategy

• 300–600 s NB

• 10–15 h total integration

Expected result A crisp planetary nebula with visible internal shells and fine structure.

Secondary February target: Small planetaries in Gemini (NGC 2371/2)
