Group of Galaxies 1, in Antlia and a red mist - first go

Revision title: Revision of colour and background

I am working on two groups of galaxies in Antlia, imaging the second one I had sever jet streams, according to Meteoblue, and that make my images not so good, within the limitation of my gear, of course.
This is the first analysis of what I called group 1, led by NGC 3358.
Nice reddish interstellar gas, as a red mist around the galaxies.

Title: Revision of colour and background

Description: A new stretch of the image, emphasizing the gas matter in the region. In the other one I used photometric colour calibration, and it turns out pushed too much to the red. This time I used just just histogram balance. You may choose which one you do prefer.

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.
