NGC2903 - A Field Barred Spiral

NGC2903 is a beautiful barred spiral, seen at an oblique angle from our vantage point. The galaxy is somewhere around 25-30 million light years away (though estimates vary). That puts it just over 10 times further out than the Great Andromeda galaxy. It is classified as a field galaxy, which means it's not gravitationally bound to any immediate neighbors (such as we are to Andromeda). Though a little smaller, many sources agree that this galaxy is similar in structure to our Milky Way. It exhibits quite a bit of stellar birth activity in the central area, as evidenced by the brilliant blue of young giant stars.

This galaxy was quite obviously missed by Messier. He cataloged many others in the area of similar brightness. The discovery credit was attributed to William Herschel.

I was able to capture luminance under two evenings, one with exceptional seeing, and the other with exceptional transparency. I did my best to blend the two attributes together. The color channels were not so fortunate. I let the data do the talking here and really tried to be light on the processing for a more natural view.

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.
