NGC4038 - Antennae Galaxies

A visually very attractive pair of interacting galaxies in the constellation of Corvus (the Crow) approximately 45-65 Million light years from Earth. They make for an impressive pair of cosmic collaborators locked in an eternal embrace.

A number of challenges presented themselves during the data capture for this object with pesky reflections caused by the light from a nearby mag 5 star and very ugly seeing. In the end I trashed all of the luminance data as the stars were too bloated though it is clear that the image didn't really need it.

Capturing an object such as this with a 5" scope and a 1.5 degree field of view requires some dedication particularly given the dynamic range spread between the core of the galaxies and the faint outer arms. To allow for this, 10 minute subs were used and at least 60 subs per colour channel were taken to improve signal to noise ratio.

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.
