Sh2-101

This image captures an emission nebula, nicknamed the Tulip Nebula, located in the constellation of Cygnus at a declination of +35 degrees. I captured this object last month in a wider FOV. This attempt with the longer focal length C11 was to try to see more detail in the nebula.

Ultraviolet radiation from stars power the emission, specifically star HDE 227018, which is the bluish star located inside the bright white arc in the central nebula region. Also, note the two prominent dark nebulae, comprised of dust, emanating from the center of the tulip, one up and one to the right. This gorgeous nebula is about 6,000 light years away from Earth. It is 25 arc-minutes wide, close to the size of our full moon, which corresponds to about 50 light years in width.

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.
