NGC3718 and its near neighbour NGC 3729 in the left of the image are galaxies that probably have interacted in the past. NGC3718 is either a spiral or lenticular, and NGC 3729 is a barred spiral galaxy. I really like this pair and also that smaller group below, and find they have a lot of interesting detail.

Processing the data was a pain, though, and I do not know why: I had a really hard time to get the colours right and the data was far, far noisier than I have come to expect from other galaxies. I have no idea why that is. Adding the data from the Atik helped some, but I just think this will need more data, that I will add in the coming seasons.

Still, with the noise reduction I did and some final tweaks in Lightroom I think this image is now ready for presentation.

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.
