NGC 4038 & 4039, the Antennae Galaxies

This is a 15.2h LRGB image of NGC 4038 and NGC 4039, also known as the Antennae Galaxies (Arp 244). They are a pair of interacting galaxies about 45 million light years away in the constellation Corvus. The object gets its nickname of the Antennae Galaxies from the two long trails of stars, gas, and dust ejected from the galaxies as a result of the collision. This target has been suggested to show the likely future of our own galaxy as it eventually collides with the Andromeda galaxy. As is clearly visible in the image, the two galaxies are currently undergoing a strong phase of starburst activity.

The small edge-on spiral galaxy towards the upper left corner of the image is the 16.4 magnitude galaxy PGC 37910.

The LRGB data were collected by DeepSkyWest in Chile in April-July 2022. I have used the new PI Generalized Hyperbolic Stretch process and only RGB stars here. PixInsight 1.8.9-1 and Photoshop CS 6 were used.

FLI LRGB 8mm filters: L:24x600s, R: 26x600s, G: 17x600, B: 24x600s. Total Exposure: 15.2 hrs

Rev G (12/23/22): Used BXT on nonlinear to reduce halos and further reduce stars. Didn't touch the galaxies.

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.
