Hello friends,

the Omicron team is very proud to present to you an extraordinary work, started 3 months ago on the Dragon trio with the C2PU's 1 meter Deltagraph.

This trio is composed of the galaxies NGC 5981, NGC 5982 (in the center) and NGC 5985. It is very aesthetic because it shows 3 different types of galaxies together.

It has here been image using the 1 meter deltagraph at f/3.2 with 15h of luminance, 4h of each RGB channel and 2h of infrared (SDSS i' filter).

NGC 5982 shows multiple shells, but also a giant stellar halo that we have never seen before. The detection was confirmed by the professionals before publishing the image and brillance measurements are in progress

A 132 x 60 s superflat with no filter has been used for the luminance to reach this LSB (Low surface brightness) halo .

We hope you will enjoy this tribute to the Draco Trio.

As usual, the final version is a 4K crop. Please have a look at the 8K full frame here, it contains an incredible amount of galaxies :

Some remarkable quasars are visible and have been pointed out by Serge Brunier. One of which is 11.8 million light years away :

Here is an inverted and stretched version to see the Halo :

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.
Dismissals 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.
