A dark molecular cloud of dust lies in the Cepheus constellation, parts of it so thick, that it absorbs all the light that comes from the stars behind it. Thanks to all the light emitted by the stars behind this dust cloud, a distinct dark shape emerges and with a little bit of imagination from the mind’s eye, one can easily recognize why this cloud is referred to as the Seahorse Nebula.

Imaging was done at the Roboscopes Observatory in Spain on the fast F2.8 Takahashi E180 scope. About 170 subs with a duration of 5 minutes each was collected and about 30 subs were deleted due to thin high clouds. The 12hrs of remaining data were sufficient to pull out enough details and contrast in the image. Star reduction was invoked to better show of the faint dust streams and tendrils. I considered cropping the image to a 5:4 or a square ratio but eventually decided against it as I felt the dark nebula is better represented against a wider swath of space…

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.
