Leo Trio (NGC3628, M66, M65)

The "Leo Trio" - There is evidence of galactic wreckage in this triplet of spiral galaxies: NGC3628, M66 and M65 (clockwise from the top of the image). The warped disk and faint tidal stream trailing to the right of NGC3628 - nicknamed the Hamburger for obvious reasons - was caused by a likely collision with M65 and M66, which has puffy spiral arms to show for it. This celestial drama plays out 35 million light years distant. Close observation of the scene reveals many additional more distant galaxies as well.

Equipment and processing used: Celestron RASA-11 telescope with ZWO ASI294 MC Pro one shot color camera riding on an iOptron CEM120-EC2 mount. N.I.N.A./PHD2 used for image acquisition. 95 individual five minute exposures (7.9 hours of data), captured on the evenings of May 16-19, 2023 from Mariposa, Ca. Processed using PixInsight.

This image was a personal challenge for me, particularly dealing with the very bright 7th magnitude star, HD 98388. This required combining two star images at different stretch levels, and 'stamping out' the residual halo in the starless image before recombining with PixelMath.

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.
