NGC 2264 The Christmas Tree Cluster and The Cone Nebula

I planned on a long integration time to get a balanced image in S-II, Ha and O-III. I was lucky to get more than a few clear nights in January and February without too much wind or moon. NGC 2264 is strong in Ha and a fair amount of signal in O-III and S-II. It's fun seeing the bright Ha subs roll-in with high signal and low noise so it's difficult to switch to O-III and S-II and spend valuable clear sky time on a weaker signal. At the end of January I began to process and found that I was needing more S-II subs so I added a couple of nights of S-II collection in February to give some nominal balance to each channel. I was pleased to see some representation in the final image of S-II, Ha and O-III in the red , green and blue color channels respectively. I also collected a fair amount of RGB for the stars but the RGB signal from the nebula regions were faint compared to the overwhelming signal of the narrowband SHO. The final image is SHO with RGB stars.

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.
