NGC 2903

NGC 2903 never seems like it is imaged as much as I would expect it to be. It is mag 9.0 and it is 11.6 x 5.7' in Leo's head. This is about a 6h LRGB integration. The mouse-over is just a cropped version. The galaxy has a nice ochre-colored bar (it is classified as SABbc) and striking collections of young blue stars and HII areas around the galactic nucleus. Notice that blue stars extend into the northern peripheral spiral arm, but much less in the southern arm. There is a complex network of dust lanes extending into the perinuclear disc. You can also see that the edge of the central bar is darker brown on the right side on its lower half, and on the left side on its upper half. The browner edge is the leading edge of the bar (it's as if interstellar dust is being swept up by it), so the galaxy is rotating counter-clockwise.

The faint dwarf galaxy at 2 o'clock is PGC-27115.

The mouse-over version now just shows increased sharpening of galactic core.

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.
