IC1396

Two panel mosaic of the huge IC1396 emission nebula consisting of hot glowing cloud of gas and dust in space where the Elephant's Trunk Nebula lies. It is located at 2,400 light years away in the constellation Cepheus and more than 100 light year across or six times the Moon as placed below with the same pixel dimension. The top right bright star is Mu Cephei or Herschel’s Garnet Star, a red super giant 100,000 times brighter and roughly 1,500 times bigger than our Sun.

I captured the bottom portion last year and this year I captured the top and bottom for some mosaic fun, so this is 19 hours for two panel sets of SII+Ha+OIII data in June, integrated and processed into a false color image using the starless technique for Hubble Palette (SII to Red, Ha to Green, OIII to Blue) resulting with white stars. The mosaic integration does not work well with unbalanced subs and unaligned rotation, some lessons for future mosaic fun project.

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.
