This is one of those forced perspective images in which it looks like a space creature is about to consume an entire galaxy, which is amusing but ridiculous, of course; like the images of people posing as though holding up the leaning tower of Pisa. In reality the galaxy that appears to be the monster's next meal, PGC 21338, lies roughly 75,000 times farther from Earth than CG4. The galaxy witnessing the carnage from above is NGC 2427.

I shot this using an Astro Physics RH305 that I rent from master astrophotographer Martin Pugh at his remote telescope hosting observatory in Australia. If you are interested in imaging the skies of the Southern Hemisphere, contact him https://www.martinpughastrophotography.space/.

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.
