Elephant 's trunk - IC1396 in Cepheus - NEW version

thanks for the Top PIck , the day of my Birthday !

A new version for this elephant's trunk with a different color palette and a complete new processing. I hope you like it !

VERSION F as final (for the moment) : my PC screen is not really calibrated ... and the original version seems a lot too dark , don't hesitate to tell me if it is too dark or too bright for your screen ;-)

----------------

This project took me a lot of patience to get the best FWHM , specifically in Halpha, but also in SII and OIII, The tuning of my EQ8 gives me now very nice guiding , after a perriod of stabilization at the begenning of each night. It improves greatly the FWHM, and the result is now much better :-)

9 nights in june and fisrt day of july : 17, 18, 19, 23, 26, 27, 28, 29, 01

85 SII Subs @300s (gain 139, -20°C)

123 OIII Subs @300s (gain 139, -20°C)

131 HalphaSubs @300s (gain 139, -20°C)

Total => 339 subs @300s = 28h 15 minutes

The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. It is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003.

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.
