NGC 4435 & 4438

NGC4435 and NGC4438 are interacting galaxies which lie in a cluster of galaxies known as the Markarian's Chain. They were nicknamed "The Eyes" by the 19th century observer, L.S. Copeland. NGC4435 (mag 10.9; dia 3 arcmin) is oval with a bright core and appears completely free of any tidal disturbances from its neighbor. NGC4438 (mag 10.1; dia 9.3 arcmin) looks as if it is the result of a merger between two galaxies. These interacting galaxies lie in the heart of the Virgo cluster and appear to be about 100,000 light-years apart today. It is estimated that they approached one another within 16,000 light-years in the cosmic past. They are about 52 million light-years away.

This is actually a combination of data I recently took and data I collected a year ago. The combination greatly helped me to bring out some of the features, particularly that of NGC4438. Given my typical sky conditions, I was delighted with this outcome.

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.
