Arp 273 - Pair of intersecting galaxies - A rose and it's stem

I've been working through Halton Arp's "Atlas of Peculiar Galaxies." In Arp 273 the larger galaxy is about five times more massive than the smaller galaxy. It is tidally distorted into a rose shape by the gravitational pull of the companion galaxy. It is thought that the smaller galaxy passed through the larger one.

This was imaged using LRGB filters in late September and early October 2022. I may go back and add another 20 hours of integration to see if I can bring out more detail.

This image is the product of an excellent collaboration with Bray Falls. In early 2020 we started working together. Bray is an outstanding Pixinsight expert who helped me come up to speed on a basic working knowledge of Pixinsight. It became quickly clear that my time was best spent on image capture and optimizing the equipment and software. Bray would work on post processing using Pixinsight, Photoshop, BXT and other software tools. I'd add a bit of LightRoom processing from time to time. I'm really pleased with the results from this collaboration which has only gotten better and better.

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.
