NGC 253 The Sculptor Galaxy (Michael Feigenbaum)

NGC 253 The Sculptor Galaxy

Here we have my attempt at NGC253 The Sculptor Galaxy.

This one is an intermediate spiral located about 11.5 million light years away in Sculptor. It is also a starburst galaxy with a lot of star formation currently ongoing. It is about 90,000 lys in diameter which places it at about the same size as our Milky Way.

Finally the smoke from the West Coast fires has subsided and that has afforded me the opportunity to get back to the telescope. This subject is located rather low in our skies at 33 degrees north latitude which allow for only a few hours of imaging per session. I have found that the quality of the sub-frames really increases once a subject attains an altitude of 30 degrees. This one was really a pleasure to do and actually went very smoothly from start to finish. Not even a big fight to process this one either, although is is very bright comparatively speaking.

I've seen a lot of images of this galaxy with varying levels of saturation. So I did struggle a bit with where I should be in that regard. The struggle for me is that I usually save my images to the staging area and then view them with different devices. My MS laptop which I think has an excellent monitor, my desktop I use for processing, my IPAD and my cellphone. The images look very different device to device. That to me is where the struggle lies. But I'm sure I am preaching to the choir with this problem, lol...

I hope you like it, clear skies and good health to you all!

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.
