NGC3690A&B AKA ARP296 & ARP299

This is an object I was curious about, and now I finally managed to image it. This is a pair of interacting galaxies, but some of the neighbours are interesting as well, like the one just to the left with the faint but very long tidal streams. It's abit like the Antennae Galaxies, only a bit more conveniently placed for northeners like me.

6 x 600s each for RGB and 24 x 600s Luminance were acquired in a single night. The flats I used were made a year ago, so I will have to redo processing... There also were some horrible gradients due to the neighbours indoor lighting early in the night and unfortunately I did not manage to get rid of all of them. Seeing was not great either, the measured FWHM was around 3 arcseconds. Still a special image to me.

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.
