NGC1313 The Topsy Turvy Galaxy - revisited

The NGC1313 galaxy was for this image acquired with the CDK24 but not with a CCD but with a QHY600 camera. Processing required a different approach to avoid blotchy small details (Bin2 was used for collecting photons, the best solution was a drizzle 2x approach with a very slight deconvolution.

As stated before, its position is within the Virgo supercluster in the constellation Reticulum. NGC 1313 has a strikingly uneven shape and its axis of rotation is not exactly in its center. its uneven shape and very rugged appearance suggests a enormous collision with another galaxy some time in the past - but there is no evidence of another galaxy, which means, that NGC1313 probably has swallowed the intruding galaxy.

The distance to Earth is appr. 12.8 Mio LJ ( some sources indicate about 20 Mio LJ) and its diameter about 50000 LJ - about half the size of the Milkyway.

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.
