The IC1396 nebula is an open cluster associated with a vast diffuse nebula in the constellation of Cepheus. Located approximately 3000 light-years from Earth, this H II region spans over 50 arcminutes in the night sky. Among its most notable features is the “Elephant’s Trunk” (vdB 142), a formation of interstellar gas and dust that stands out against the starry background. The nebula is illuminated by the young blue stars of the Cepheus OB2 association, whose ionizing radiation has created a ring of molecular gas. Within the nebula, there are numerous dark globules, dense regions of star formation.The image was captured using a Tecnosky AG70 astrograph and a monochrome ZWO ASI2600MM PRO camera. 54 narrowband frames of 600" for 9 hours total integration. Despite challenges from weather conditions and light pollution, careful selection allowed for the integration of the best images, discarding a greater number of shots than those used.The final processing was done with Pixinsight software. Two different palettes were selected:- The Foraxx Palette, which is based on the contrast between the rust tones of S II and the blue tones of O III, while Ha is used to modulate the red and blue. This palette creates an image with vivid colors and fascinating details, using dynamic PixelMath expressions to combine the narrowband images.- The CFHT Palette, which is named after the Canada-France-Hawaii Telescope, and which uses a different combination from the classic Hubble Palette, assigning S II to the green channel, O III to the blue channel, and H-alfa to the red channel. This palette creates an image with particular gold and purple tones, highlighting the different emission regions of the nebula.

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.
