Added OIII to the Ha data on this target for the HOO rendering. This was a task as the target is quite low from the Beevo Dome and there were way too many satellite and plane streaks. Thanks to MJ for guidance on their removal using PixInsight's "Reject high large-scale structures" during stacking; worked a treat!

As mentioned in the Ha post, this image covers a part of a huge HII area in Ophiuchus which spans 13°. The dual Borg 55FLs and ASI 2600MM Pros did a good job gathering data. The bright star in the lower right is Zeta Ophiuchi. Note the small globular bottom left, M 107; the bright nebulosity at lower right is LBN 35.

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.
