IC 1396

This is IC 1396 otherwise known as the Elephant Trunk. It looks more like an Elephant Trunk in a wider field. This image was taken on an Esprit 150 with 1050 mm focal length. Consequently, I basically have all nebula in the image. This created problems with color calibration (I could not get a good sample of background) in Pixinsight but that turned out to not be necessary due to a very good background extraction in DBE and the very dark skies at Pixelskies. Many thatnks to Ron Brecher of Masters of Pixinsight for the help he gave me on how to process this image. His turoring was extremely helpful and now I feel that I am finally getting a handle on Pixinsight. I still have a lot to learn but it is good exercise for my old brain.

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.
