4.7 magnitude Alsafi (sigma draconis) sits amongst some dusty nebulae - LBN464, 465, 469, 481 - in the constellation of Draco. I chose this target after I spotted the area in Sky Safari and then reviewed it in surveys in Aladin. I could tell there was something there, but not much, and as I could find no other images, I thought I'd have a go. If nothing else, it proves there really isn't much there!

I looked up Alsafi, and I like this Wikipedia quote (hopefully true) - "It bore the traditional name Alsafi, derived from the Arabic Athāfi, itself erroneously transcribed from the Arabic plural Athāfiyy, by which the nomads designated the tripods of their open-air kitchens". So really Alsafi in Arabic was referring to the trio of stars sigma, tau and epsilon draconis.

Anyway, it's rather bright, and I've not really been able to reduce its impact, so I might as well include it in the title! As I often do with RASA images, I removed stars for the nebula processing, and then added back. I found this didn't work very well with Alsafi, and I had to bring it up quite a bit using a mask in order to remove artifacts relating to the large halo and reduced star. Overall this image required some fairly curvy curves, and this has also meant that other brightish stars across the frame have halos from the background stretch. I'm not going to try and remove them, so this is it.

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.
