Description

This is the eighth panel in the 18-panel mosaic shot on 19 different nights between between February 19, 2021 and April 11, 2021. This image is more interesting than some of the panels in the mosaic because it sports a tightly grouped sub-cluster of galaxies stretching from NGC 4469 in the lower center to NGC 4380 near the upper right.

(This is Panel 11 in the mosaic sequence set forth here: https://astrob.in/costym/0/)
