Xmas Tree Cluster

After a really long time of clouds I finally got a night with clear skies. These are the first results of shooting with my new DIY harmonic drive mount that I have decided to name the OpenHarmony Mount.

Here you can see the Christmas Tree cluster, an open cluster of stars located within all the nebulous gasses of NGC 2264. These stars are fairly young, and were formed between 1 and 4 million years ago from the surrounding molecular cloud. The open cluster is home to at least 600 stars. This was a total of 66 shots of 3 mins each.

These results were obtained with an average guiding error of 0.62 arcsecs which is extremely good performance. I will be fine tuning the mount and design which will be released as an open source project, as well as pre-made kits for a very fair price.

Feel free to DM me for more details.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
