NGC 4945 in Centaurus Constellation ** Release 2 and Release 3 ** (Fernando)

NGC 4945 in Centaurus Constellation Release 2 and Release 3

NGC 4945 is one of the brightest galaxies of the Centaurus A/M83 Group, and the second brightest galaxy in the subgroup centered on Centaurus A.

Its apparent size is 20' x 3' and apparent magnitude 9.3. It is distant from Earth by 11.3 million Light Years.

Please look carefully to see the great number of little galaxies spread out all over the surrounding space.

The image was taken with the following stack:

Luminance: 20 x 10 minutes bin 1x1

RGB: 10 x 10 minutes bin 1x1 each channel

Instruments:

Scope: RC-8" f/8 (no flattener or reducer)

Camera: ST8300M

Mount: EQ-6 Pro guided

Pre and Post Processing: Pixinsight

Bias, Darks and Flats applied

A note about ** Release 2 **

I did two things different with respect to the R-1

1- Applied a more agressive deconvolution on the luminance channel.

2- Pulled the color contrast of the final image still in FIT file format

A note about ** Release 3 **

A more neutral background has been achieved. Other than that, the image is the same of the Release 2

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.
