IC 1459 Galaxy Group in Grus featuring NGC 7418 in RGB (Ian Parr)

IC 1459 Galaxy Group in Grus featuring NGC 7418 in RGB

IC 1459 (also catalogued as IC 5265) is an 10th magnitude elliptical galaxy 5'.2 × 3'.8 in size located in the constellation Grus and the dominant member of a galaxy group known as the IC 1459 group which is a loose group centred at IC 1459 and contains a large number of spiral galaxies.

It is located at a distance of circa 85 million light-years from Earth, which, given its apparent dimensions, means that IC 1459 is about 130,000 light-years across and was discovered by Edward Emerson Barnard in 1892.

NGC 7418 is the very pretty magnitude 11.39 face on spiral in this image with an apparant size of +0°03'47.58" x +0°02'02.88".

This group, along with the NGC 7582 group, form the Grus cloud, a region of elevated galaxy density. The Grus cloud, along with the nearby Pavo-Indus cloud, lies between the Local Supercluster and Pavo–Indus Supercluster.

My cool winter plunged rapidly into summer over the last few nights. QSI CCD cooling went from -24C to -13C over the space of a few nights with some wobbly seeing so conditions were not ideal but it's a new moon so I did manage two long RGB runs which helps make up for the conditions.

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.
