Virgo Cluster Mosaic

After many tries and versions, I am happy to finally publish my final version of my Virgo Cluster Mosaic.

This image is composed of 4 panels, all over different nights between February and April 2021.

Each panels were stacked in Astropixel Processor.

App was also used to create the mosaic, crop, remove light pollution and calibrate star colors. I tried all this with Pixinsight and found the end result was better in APP.

I also created a stretched version from APP for later use, to integrate the stretched galaxies in final image.

Each panel has about 3.75 h of data for a total of 14 h 17 minutes of total ight integration. I will add the detailed information for each panel later.

Pixinsight was used to apply noise reduction on the linear data. I then did a small stretch and used starnet to remove the stars.

From there, I opened the starless image in Photoshop to fix some gradients, mostly where the panels were stiched.

I opened the stars in Photoshop as well and applied noise reduction on each channels.

Went back in Pixinsight and used PixelMath to recombine the fixed background with the new stars.

Swtiched to photoshop to copy the streched galaxies (from the App stretch) on top of the image and blend them togheter.

Final touch up in PS to remove some magenta in the galaxies and applied final noise reduction using Adobe camera raw.

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.
