Barred spiral galaxy NGC 2903

Link: https://astrovirusblog.wordpress.com/2018/03/22/ngc-2903-a-jewel-in-leo/

This small galaxy was going to be a real challenge due to the enormous amount of light pollution at my location and limited resolution of my wide-field telescope.

The barred spiral galaxy NGC 2903 is similar to our own Milky Way and lies about 30 million light years away from us.

I was quite surprised to see some of the faint outer spiral arms. Detail in the core was improved with drizzle stacking and deconvolution. The luminance data was then down-sampled again to native resolution and further used without any noise reduction. I tried to be a bit conservative with color saturation of the galaxy and stars.

The original wide field image also contains spiral galaxy NGC2916 (magnitude 12) near the bottom and many small galaxies in the background, see Rev. B for annotation.

It is presented in Rev. D with a more artistic crop/rotation to show the largest galaxy along a group of small, very distant galaxies on the right side.

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.
