IC1848, also named the Soul Nebula is a magnificent (from my perspective of course), emission nebula that I already took in 2020/2021 when I was equipped with a RASA C11 scope. However, at that time I didn’t have the skills to generate a publishable image. So, I did capture again the nebula with my TV127 refractor and 10Micron mount to obtain a well detailed Ha layer. So, after accumulating 268 subs of 180s each, I obtained the level of details aimed while keeping some smoothness around the details. Then I compiled the SII and OIII layers from the RASA C11 (not such an easy task to manually match the layers with different focal lengths, if you have suggestions I am interested…), as well as the RGB for the stars. Obtaining the final image was also not so straight forward as the nebula is quite strongly contrasted, so one may end with a rather “artificial” image. I hope that you will enjoy this version.

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.
