The Dragon 'Lonely' galaxy - NGC 6503

NGC6503 is located near the 'Local Void' in the Draco constellation at ~18 MM l-y from Earth. This dwarf spiral edge-on galaxy is 'alone' near the 'Local Void', an area of space depleted in stars and galaxies. Most galaxies occur in groups but NGC6503 is name 'solitaire' as it stands alone near a huge patch of darkness some 150 MM ly across.

NGC 6503 has a magnitude of 10.2 and apparent size of 7 x 2.4'. NGC 6503 is colorful with star forming regions (Ha) in the spirals and brown lanes of dusts create a 'flocculent' texture (reference NASA and Wikipedia).

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.
