<\/figure><\/div>\n\n1. M42 <\/strong><\/h5>\n\nRecommended equipment: Small\/medium or large telescope<\/strong><\/p>\n\nWe\u2019ll start in Orion\u2019s Sword where M42, the Orion Nebula, takes pride of place. Magnificent through any instrument, smaller scopes give a lovely overview of this fourth-magnitude nebula, easily revealing the bright kidney-shaped \u2018core\u2019 within which the tightly packed stars of the Trapezium Cluster are embedded. The swept-back \u2018arms\u2019, the Sail and (confusingly) the Sword, are obvious, giving M42 its distinctive shape. Larger scopes let you explore tendrils of excited hydrogen. Under very dark skies it may be possible to see the swept-back arms reconnect to form a loop. The nebula is around 24 lightyears across and 1,340 lightyears from the Sun. It\u2019s also the closest star-forming region visible from Earth. <\/p>\n\n
2. M43 <\/strong><\/h5>\n\nRecommended equipment: Small\/medium or large telescope<\/strong><\/p>\n\nEight arcminutes north and slightly east of the Trapezium sits the comma-shaped emission nebula known as M43 or De Mairan\u2019s Nebula. Smaller instruments show a smooth nebulous region with seventh-magnitude variable NU Orionis slightly offset from the centre. NU (not to be confused with Nu (\u03bd) Orionis) powers the nebula, causing it to glow. The distinctive comma shape doesn\u2019t become apparent until you go above 250mm of aperture. M43 appears separated from M42 by a dark dust lane, itself extending towards the Trapezium to form a dark feature known as the \u2018Fish\u2019s Mouth\u2019. M43 is 1,300 lightyears distant and around 2.1 lightyears across. <\/p>\n\n
3. NGC 1977 <\/strong><\/h5>\n\nRecommended equipment: Small\/medium or large telescope<\/strong><\/p>\n\nHead 26 arcminutes north from NU Orionis in M43 to arrive at a distinctive group of three stars: mag. +4.6 42, mag. +7.3 V359 and mag. +5.2 45 Orionis. The trio are surrounded by the east\u2013 west band of reflection nebulosity, NGC 1977. The brightest part of this 40 x 25-arcminute nebula sits south of the three stars. A darker area south of the western part of the nebula creates a distinctive scalloped-out southern boundary. The whole region is part of Sh2-279, named the Running Man Nebula because of the silhouetted figure formed from darker lanes crossing NGC 1977 and in between the brighter nebula and two smaller nebulae to the north: NGC 1973 and NGC 1975. The Running Man is best \u2018seen\u2019 through long-exposure photography. <\/p>\n\n

IC 434<\/strong><\/h5>\n\nRecommended equipment: Large telescope<\/strong><\/p>\n\nNext is emission nebula IC 434. Head north to mag. +1.7 Alnitak (Zeta (\u03b6) Orionis), the eastern Belt star. Look 50 arcminutes southwest to mag. +3.8 Sigma (\u03c3) Orionis. Head 31 arcminutes east-southeast of <\/p>\n\n
Sigma to mag. +6.2 HIP 26713, then mag. +6.4 HIP 26820 16 arcminutes further east still. IC 434 appears as a linear curtain of nebulosity, its brighter and straighter edge running from Alnitak to a point between HIP 26713 and 26820. It is hard to see so dark skies, an aperture over 250mm, and a hydrogen-beta filter are recommended. Identify mag. +7.5 HIP 26756 using our chart and try to see the small dark notch interrupting IC 434\u2019s curtain. If you see this, well done \u2013 you\u2019ve found the Horsehead Nebula! <\/p>\n\n
5. NGC 2023 <\/strong><\/h5>\n\nRecommended equipment: Small\/medium or large telescope<\/strong><\/p>\n\nThe Horsehead can be tough even with a large telescope. Thankfully, our next target is easier. Look 10 arcminutes east-northeast of HIP 26756 (see target 4) to locate mag. +7.8 HIP 26716. You\u2019re now looking at the heart of NGC 2023. The nebulosity may not be obvious at first as it looks like a smooth, misty glow around HIP 26716. A small scope shows this well. Looking carefully it should be possible to see that it extends further east than west. A large telescope shows details, with darker patches breaking the nebula\u2019s smoothness. <\/p>\n\n
6. NGC 2024<\/strong><\/h5>\n\nRecommended equipment: Small\/medium or large telescope<\/strong><\/p>\n\nOur final target is simple to locate and relatively bright at mag. +10.0, but if this sounds like an easy end to the tour, think again. NGC 2024 sits 15 arcminutes east-northeast of Alnitak, whose light makes the nebula hard to see. A 150mm scope reveals a large 11-arcminute patch crossed by a 3-arcminute-wide dark lane running southeast to north, curving northeast at the last minute. Larger instruments should hint at more dark tendrils emanating from the central lane like a candle flame. This is NGC 2024, the Flame Nebula. <\/p>\n\n
