Antennae Galaxies and friends

Revision title: Revised

I think this is a fascinating target. I captured this last year with a 127mm refractor, this time I went after it with my 8" mak/newt, next I may try my 11" SC. In 2 night I got 8 hours that I added with the 8 hours from last year. Captured another decent sized galaxy (lower left NGC 4027) which is a barred spiral galaxy 77 million light years away. You can also see, PGC 37910 (below and to the left), which is a spiral galaxy about 79 million light years away, plus several other PGC galaxies.

I also added a cropped version of just the Antennae Galaxies.

This is 2 interacting galaxies (NGC 4038 & 4039) were discovered in 1785 and originally thought to be a planetary nebula. These galaxies are about 63 million light years away. It is estimated that the collision of these 2 galaxies happened about 600 million year ago. The ejected stars which create the 2 antennae span around 360,000 light years across.

Description: Light stretched in APP, stars extracted in PI, PI generalized stretch, touch up in PS. I think the galaxy, stars and background look better on this image, but the Antennae's a not bright and noticeable. Always a fine line on how hard to stretch and push the image.

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.
