On any autumn or winter evening, scan between Cassiopeia and Perseus for the magnificent #DoubleCluster in #Perseus. The #stars in these 2 clusters are young, hot supergiant suns that are many thousands of times more luminous than our sun. 🌌🔭

On these dark evenings the Perseus Double Cluster and the Andromeda Galaxy, M31, await in the northeast. They're only two fist-widths apart.

Between constellations Cassiopeia and Perseus, the Double Cluster (NGC 869 & NGC 884) sparkles with 7,500-year-old light, as a satellite streaks through orbit.

A Double Star Cluster in Perseus

Breathtaking image of the Double Cluster (h and chi Persei, NGC 869 and NGC 884) in the constellation Perseus. These two open star clusters, visible to the naked eye under dark skies, are only a few hundred light-years apart and share a similar age, suggesting a common origin. Cataloged by Hipparchus in 130 BC, they're a stunning binocular target, showcasing bright, young stars against the backdrop of the night sky.

I think the #DoubleCluster is my favourite cluster #Astrophotography

Here is another I took under Bortle 3 skies. I had limited time so I went with a bright target. This is 4 hours integration with a RC6 with a ASI2600mm and a frosty mug full of Speedgoat from Ten Sleep, WY, USA #astrophotography #deepspace #doublecluster #deepsky #stars #astronomy
The Double Cluster or NGC 869 is a set of two independent loosely bound star clusters in the constellation Perseus. Each star cluster has about 150 - 200 stars and are mostly young stars with a scattering of older cooler stars.

A stunning wide-field image of the Double Cluster (NGC 869 and NGC 884) in the Perseus constellation. The vibrant image showcases two prominent open star clusters, surrounded by reddish emission nebulae and countless stars. A smaller, fainter open cluster, NGC 957, is visible in the upper left. This color composite highlights hydrogen gas emission, revealing the intricate details of this rich star-forming region approximately 7,000 light-years away.

Stunning image of the Double Cluster (NGC 869 & NGC 884) in the Perseus constellation. These two open star clusters, easily visible with binoculars, are only a few hundred light-years apart and share a similar age, suggesting a common origin. Cataloged by Hipparchus in 130 BC, they are a breathtaking sight from dark skies, showcasing a rich tapestry of young, hot stars against the backdrop of the cosmos.

While watching the #Perseids2025 last night I separately set the scope to catch 60 mins imaging on #Caldwell14 #DoubleCluster in #Perseus - I don't usually do mosaics but seemed appropriate for tonight #EAA #Astro #astronomy
