HD 39881 (S 503): A Wide Double Star in Orion

Orion is a prominent winter constellation known for its bright stars, including Betelgeuse and the Orion Nebula, as well as double stars like S 503. This system, consisting of components A and B, offers viewing opportunities with binoculars and telescopes. Recent observations highlighted their visibility despite fading dawn light. Also known as SAO 95004, HD 39881, HR 2067, HIP 28066, BD+13 1036, GC 7469, 0728-03142-1

The Horsehead Nebula (IC 434): A Shadow in the Stars

The Horsehead Nebula, located in Orion, is recognized for its iconic silhouette but is faint and challenging to observe. First discovered in 1888 by Williamina Fleming, it is a stellar nursery contributing to star formation. Ideal viewing occurs between December and March, away from city lights using larger telescopes.

Struve 700 (V1804 Orionis): Double Blue in Orion’s Winter Cool

Learn about the double star in Orion called Struve 700 and V1804 Orionis. The pretty set of blue-white stars shine around 7.8 magnitude and are a tight pair in telescope. My sketch shows what the binary looks like through a backyard telescope. They are a great pair to seek out when observing through Orion, the hunter, on winter days.

NGC 2169: A “37” Tattooed on Orion’s Outstretched Arm

High above Orion’s Nebula and belt lies the star cluster NGC 2169, affectionately known as the “37 Cluster.” This arrangement of stars earned its nickname due to its resemblance to the number 37 when viewed through a small telescope or binoculars. It’s also known as Collinder 83, XY Cluster, and the LE Cluster

Meissa (Lambda Orionis): A Luminous Multiple Star in Orion

Marking Orion’s head is the bright star, Meissa. But it’s more than that. Aim your binoculars or telescope toward Meissa, and you’ll find a beautiful grouping of related stars. The star is also known as SAO 112921, HD 36861, Lam Ori, Struve 738, STF 738, HD 36861, λ Ori.
