NGC 2903 and NGC 2905 in LRGB

This image is one of my trial and error images, wanted to see how much one can get out of 2 minute exposures (compared to my often used 5 minutes).

All in all I am pretty ok with the image, there are quite some details to see. I still do not think that the quality reaches 5 min exposures, but that might be also related to the total integration time, which is significantly less than my 5 min exposures. But it fit so well into my schedule for all the targets that I aimed for, hence this limitation. Which means as well that I need to do another trial with 2 min exposures and many more images, oh well ... I guess I am fine with that 😊.

The Plate Solving mentions as well NGC 2905: According to Wiki: NGC 2905 now designates a luminous knot in the northeastern spiral arm, which now makes sense, I thought first this was in some form a galaxy merger, but could not see it.

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.
