IC 1396 (SHO)

The image was captured using a TS Hypergraph 8" f3.2 telescope, a ZWO ASI 294MM Pro camera, and Antlia V Pro 3nm filters (SHO). It was mounted on a Skywatcher Eq6-r-Pro mount, using an OAG+QHY5L-M. The software used included Sequence Generator Pro, PHD2, Pixinsight, and Adobe Photoshop.The image is a binning 1x1 SHO composition. The exposure details are SHO (3x30x300s), totaling 7.5 hours of exposure.
In the constellation of Cepheus, we find an area with numerous structures of dark nebulae interspersed with a large emission nebula, highlighting the structure known as the Elephant's Trunk. This is an area dominated by a multiple star system with a magnitude of 5.7, with the main star being a blue giant of spectral type B. They are located within the open cluster Cr 439. The intense radiation emitted by the multiple stars ionizes a large region around it, causing the observed emissions in the SII-Ha-OIII wavelengths and, in contrast, revealing the abundance of dark nebulae in the area. Inside the Elephant's Trunk, a reflection nebula VdB 142, illuminated by a B-type star, can be observed. Crossing the center of the image, you can see the dark nebula Barnard 161 in black.

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.
