NGC 3718 and NGC 3729

This represents a month of waiting for one more clear night to get enough data to process, and my latest foray into imaging at 2800mm unguided.

In the center of the field of view, we have NGC 3718, which is a lenticular spiral galaxy that is 52 million light-years away from Earth. To put that into greater perspective, it means we are observing this galaxy as it looked when Australia and Antarctica were still connected during the Eocene epoch.

To the right of center, we have NGC 3729, which is a barred spiral galaxy that is 62 million light-years away from Earth. This fun fact reminds us that even though the two galaxies appear in the same plane, they only appear this way because everything appears two-dimensional so far away from Earth. Although they are captured in the same picture, the distance between NGC 3718 and HGC 3729 is 150,000 light years. The scales here are really beyond comprehension.

Not to be outdone, the cluster of "small" galaxies above NGC 3718 is the Hickson 56 galaxy group, which are 425 million light-years away.

Hope you enjoy the picture, and these fun facts as much as I did learning about them!

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.
