NGC2903

Acquisition type: Lucky imaging

This image set sat in my "need to process" bin since early 2022. I thought the data didn't look hopeful, from home observing nights with so-so seeing, moon, only bin2x2, etc so I just never went and processed it. I also had 17 minutes of data (clouds ruined the chanced of capturing more) from a dark sky site with much better seeing that picked up a lot of core detail.
So I processed both sets of data and combined them and with a little TLC, the results came out a far better than I expected. It's amazing how bad some of the input data can look before processing transforms it into a astro image!

The galaxy as a whole is NGC 2903 at a distance of around 9.2 mega-parsecs, while NGC 2905 appears to be one of the large brighter HII regions near the upper end of the bar.
The faint galaxy to the left just below center is low surface brightness galaxy UGC 5086 at a distance of roughly 7.4 mega-parsecs.

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.
