The Draco Dwarf Galaxy

The Draco Dwarf Galaxy is a spheroidal galaxy located 280,000 light years away, residing in our Local Group. It was discovered in 1954 by Albert George Wilson of Lowell Observatory on photographic plates from the Palomar Observatory Sky Survey (POSS).

The Draco Dwarf is extremely dim and diffuse, so my goal for this project was to gather enough data to make the galaxy standout somewhat from the background. One of the challenges I faced with this project was an early start to wildfire season in the South Western US. Although skies have been relatively clear lately they have been smokey, so I have attempted to images on nights with the best seeing and transparency at times of low moonlight. I gathered more data that I needed so that I could mercilessly reject data that did not contribute to the overall image.

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.
