Around the Iris

Few clear nights in mid May with the New Moon were a blessing, though at 52N latitude the contrast was already very poor and even under Bortle 3 the sky was quite bright. I have grabbed some Antares frames and decided it is not really clever to try and shoot on 8 deg altitude. Thus, I have decided to spend two nights depicting the surroundings of the Iris. Each night gives a bit over 3 hours of moderate darkness and this was my only chance at getting a reasonable stack.

Notice the hydrogen areas, in the right corner next to Alderamin, alpha Cephei, 5 Cep, close to the Elephant Trunk (which sadly didn't fit in my frame) and the young stellar object with a magenta-red glow in the upper right close to the big white star Al Kidr, theta Cephei, 2 Cep.

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.
