NGC 3628 the Hamburger Galaxy in Leo

Florence and Linslaw Point, Oregon

March 25 – April 13, 2020
Reprocessed 2/1/2023

NGC 3628, the Hamburger Galaxy, was captured with broadband filters, Luminance, Red, Green and Blue. This edge-on galaxy is located in the constellation Leo. NGC 3628, M65 and M66 form the Leo Triplet, three gravitationally interacting galaxies. NGC 3628 is fainter than its companions, which is why Charles Messier missed it. It is about 35 million light years from Earth and is about 113,000 light years across (SkySafari Pro). There is a faint tidal tail of stars in the upper left part of the frame, likely caused by gravitational interactions with M65 and M66. The disk is also highly distorted from these interactions and perhaps from a past merger with another galaxy. There is also a small companion galaxy below the center of NGC 3628.

Since the 2021 galaxy season is beginning and Western Oregon has been suffering endless cloudy and rainy nights, I reprocessed the 2020 data in Pixinsight using my new workflow for handling RGB color and luminance images separately. The image really needs much more luminance and some more R, G and B subframes in order to bring out the elusive tidal tail.

The new version was reprocessed in PixInsight using new tools and an improved workflow.

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.
