The Christmas Tree Cluster (NGC 2264) resembles a Christmas tree, with the Cone Nebula as the ornament at the top. It was captured from Qixingtan in Hualien, Taiwan, a Bortle 3 zone. The telescope was my Celestron EdgeHD 8" and HyperStar v4 configuration. I tracked the object with my Celestron AVX mount and imaged it with my ASI533MC Pro camera. The acquisition time consisted of 45 light frames, each at 180 seconds.

The Christmas Tree Cluster
=====================

My last capture of the year 2024 is the Christmas Tree Cluster and Cone Nebula in the constellation Monoceros. This region is a fantastic sight in the night sky, with the Cone Nebula and the Christmas Tree Cluster forming the iconic structure in the center. While not officially part of this designation, the Fox Fur Nebula and the Snowflage also are prominent parts of this region.

The Cone Nebula is an H-II region. It's shape is created by a dark absorption nebula and dust in front of the faint emission nebula.

Left from the central structure, there's a small bright nebula, easy to miss. This is Hubble's Variable Nebula, named after Edwin Hubble, who studied it in the early 20th century - the first recorded observation however was done by William Herschel in 1783. The nebula is illuminated by the star R Monocerotis, which is a young variable star, and changes it's appearance visibly over just weeks.

Finally, below the central structure and right from those dark nebulae, there's NGC 2259, an open star cluster.

To wish you all a happy Christmas here's my photo of the #ChristmasTreeCluster + #ConeNebula. Thanks for all of the likes/comments/RTs, for listening to the #StarDiary podcast & for the amazing support since the release of the Collin's Stargazer's Bible. I'll be taking some time out over the festive period, but I'll be back in 2025. Mary x

#SkyWatch #Astrophotography #NGC2264 is part of the #Monoceros region of the Milky Way and contains 4 nebulae that are between 2300 and 2700 light years from Earth:. The #ConeNebula is on the far left. The #ChristmasTreeNebula looks like it is lying on its side with the Cone at its top,. The #SnowflakeNebula is bluish white. And the #FoxFurNebula is on the far right. This image is 17 three minute exposures that I captured Friday night stacked with calibration frames. #StillLearning

Say hello to Cone Nebula 👋 This magnificent entity (not the Crystalline one 🖖) is seven light years long and the product of newly created stars letting off wind after their Christmas brussels (science FACT). Picture from @esoastronomy on account of their 60 year anniversary. Thank you @shaman for the original share. #ConeNebula #ESO #VLT #Astrodon #AstroChatter #astrophotogrphy
