NGC 55 The String of Pearls Galaxy in Sculptor in RGB

NGC 55, the String of Pearls Galaxy in Sculptor, also referred to as The Whale Galaxy, is a Magellanic type barred spiral galaxy located about 6.5 million light-years away.
Along with its neighbour NGC 300, it is one of the closest galaxies to the Local Group, probably lying between the Milky Way and the Sculptor Group and it is likely that NGC 55 and NGC 300 form a gravitationally bound pair. It has an apparent magnitude 7.87 and is quite at 32.4 x 5.6 arcminutes.

This combines the best 4 hours data from over 6 hours taken the last two years with a good run into the early hours from last week.

Wow! The latest Pixinsight update fixed some huge issues with performance, like Image Solver times slashed from minutes to seconds, and that performance lift is showing up in other tools so that sort of makes up for the changes to the dialog boxes defaults that really messed around with muscle memory.

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.
