NGC 6140 in Draco

Link: http://www.jthommes.com/Astro/NGC6140.htm

North is up in this image. NGC 6140 is a barred spiral with peculiar features. It is classified as SB(s)cd pec. The central bar is easily seen but with some distortion at its northern end and the associated spiral arm is somewhat disconnected from the central bar. NGC 6140 has a redshift independent median distance estimate of 26 million light years. But of the three measurements taken for this galaxy, there is a fair bit of uncertainty - with a STD DEV of 9+ million light years. The distance estimated by redshift is 42 million light years. There are numerous background galaxies in this field - but most with neither a redshift or independent distance estimate. The one other galaxy in this field with a distance estimate by redshift is UGC 10376; the distance estimate is 150 million light years. These galaxies and some of the brighter stars are identified in the annotated image. Horizontal FOV is approximately 38 arc minutes (0.85 arcsec/pix image scale on the full size 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.
