La galaxie NGC6946 dans Céphée. Image LRGB de 165, 25, 25, 37mn, Télescope Meade LX200 ACF de 2500mm de focale et ccd CP8-MS. Cette spirale à 4 bras possède de nombreuses condensations correspondant à des régions de formation d'étoiles. Elle est distante de 12.25 millions d'années lumière et on y a détecté pas moins de 9 supernovæ depuis le début du XXe siècle;

Galaxy NGC6946 in Cepheus. This is a large and bright four-branch spiral galaxy with a small, brighter core obscured somewhat by a dust patch. Four spiral arms are distincly seen; they are marked by many condensations indicating star clusters or star forming regions. Owing to the galaxy low galactic latitude, considerable light absorption by dust in the plane of Milky Way may be dimming the galaxy. There have been a large number of supernovæ in this galaxy over the years (1917, 1939, 1948, 1968, 1969, 1980, 2002, 2004, 2008). With a distance of 12.25 mly., it is one of the nearest galaxies of theLocal Group. Angular size 11.5'x10.0', dimeter 40 500 ly.

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.
