Easily visible with the naked eye, M45, The Pleiades – sometimes referred to as The Seven Sisters, is a well known and famous Open Cluster in the constellation of Taurus.  IT has been known since ancient times due to its prominence.  The cluster is located between 450-500 light years away and contains several hundreds member stars.  The cluster is quite young by astronomy standards and the cluster is moving through a cloud of gas which is easily visible in images and can been seen visually in a dark sky as well. M45 – THe Pleiades Technical Details Imaged from my backyard in Nottingham on Saturday 9th January 2021 when high to The South.  A meridian flip occurred half way through the data acquisition.  I used my Takahashi FSQ85 refractor and QHY268C One Shot Colour camera.  The image was created with quite a small data set of only 38 x 180s…

M38 is the third of three Messier Open Clusters in the constellation of Auriga, in the Northern hemisphere of the sky. The other two Messier clusters are M36 and M37. All of them are easily visible with binoculars and are seen as faint smudges against the darker background. If you read my post on the Constellation of Auriga you will see all three of the Open Clusters in the same image M38 Open Cluster Image Technical Data Imaged from my back yard in Nottingham, UK on the 18th January 2020 whilst high overhead from my location. I used my TEC 140 refractor with Atik 460 cooled CCD camera and Astrodon RGB E Series Generation 2 filters. I used my MESU 200 mount guided with OAG. All exposures binned 1×1: Red > 12 x 180s ; Green > 14 x 180s ; Blue > 13 x 180s. This gives a total integration…

M39 is an open cluster, about 1100 light years distant, in the constellation of Cygnus, The Swan. M39 is about 30 arc minutes in diameter, about the width of the full moon. The Cygnus constellation abounds in interesting objects and The Milky Way galaxy flows straight through it. M39 Open Cluster in Cygnus ImageTechnical Data Imaged from my backyard in Nottingham, UK on the 16th October 2019 when it was high overhead from my location. I used my TEC 140 refractor and Atik 460 cooled CCD camera with Astrodon RGB E Series Generation 2 filters. I used my MESU 200 mount guided with an off-Axis guider. All exposures binned 1×1: Red > 15 x 120s ; Green > 12 x 120s ; Blue > 15 x 120s M39 Annotated M39 Inverted I hope you like it! 🙂

M37 is one of the three Messier Open Clusters in the Constellation of Auriga – the other two being M36 and M38.  It is about 4500 light years away and contains several red giant stars, visible in this image, making it the richest of the three Auriga Messier Open Clusters. M37 appears high overhead from my 53 degree norther location during the winter months making it an ideal target for visual observations and imaging.  It makes a fine site in a telescope and appears as a fuzzy ball in a pair of binoculars. M37 Image Technical Data Imaged from my backyard in Nottingham, UK on the 9th February 2018.  I used my Takahashi FSQ85 refractor and Moravian G2-8300 cooled CCD camera with Astrodon RGB filters.  All expsoures are binned 1×1.Red > 12 x 120s ; Green > 12 x 120s ; Blue > 12 x 120s M37 Annotated Version M37…

M44 or “Praesepe” as it is called, is a famous open cluster visible in the late winter/ springtime in the constellation of Cancer – The Crab. It is often nicknamed The Beehive cluster since it resembles a swarm of bees when viewed in a wide-field telescope or binoculars. Along with M45 it is one of the most immediately breathtaking sights in the deep sky. At about 510 light years it is one of the closer Open Cluster to the Earth and is about 12 light years across and contains about 1000 stars. Note the tiny, distant galaxy in the bottom of the cluster PGC24400. M44 (“Praesepe”), The Beehive Cluster Image Technical Data Imaged over two evenings, the 22 and 23 February 2019 from my backyard in Nottingham, UK. Conditions were far from ideal with a high, hazy mist that made transparency poor and subsequent processing difficult. Captured with Takahashi FSQ85…
