Cheshire Cat Galaxy Cluster (gravitationally lensed galaxies)

This is an experiment, I heard about this object and wondered what would be visible if I tried to image it. So I took 25 Luminance integrations of 600s each, and added 3 x 600s each for G and B, and 6 x 600s for R.

To my surprise, I could even detect the arcs (very faintly) on a single integration. Judge for yourself, almost exactly in the middle of the image there are two very small and faint dark orange galaxies with faint hints of arcs around it. A nice comparison image can be found on the Hubble Space Telescope images website: A smiling lens

My image is rotated 90 degrees clock wise compared to this Hubble image, can you spot the cat's face?

I made a Comparison Image that shows the ESA/Hubble photo on the right, also available in revison B.

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.
