Cone/Christmas Tree Nebula NGC2264 (Bi-Color NB)

This uncropped image represents a wide field effort of the Cone/Christmas Tree Nebula complex NGC2264. I typically use a unity gain of 111 for both of my ASI183's, but tonight I jacked it up to 200 to see what kind of results I could get. I've also had very good results stopping down my Canon 200mm lens from f/2.8 to 4.0. This has helped with better focusing and mitigation of any chromatic aberrations that results from using the L-eXtreme filter. My main concern was being able to calibrate out the amp glow successfully at this gain level. This was also the second time that I used the new polar alignment utility on my ASIAIR Plus, which allows me to polar align without having to see Polaris. This new feature actually worked very well, and allowed me to place my mount and scope right outside my front door. Processing the results, I was pleasantly surprised to also see the Hubble Variable Nebula NGC2261 in the frame. I didn't think that I could see it at 200mm FL.

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.
