Description

This image is a combination of the first four panels (numbered 3, 4, 9, and 10) in the 18-panel mosaic of the Virgo Cluster shot over 19 nights between February 19, 2021 and April 11, 2021. Inching closer panel-by-panel.

I hope I’m doing this right and not violating any sense of etiquette by posting each panel and the intermediate mosaics separately. Please let me know if you think these should be posted as image revisions rather than separate images. I have 14 panels and at least two more intermediate mosaics to post before I get to the end here.

(This is Panels 03, 04, 09, and 10 in the mosaic sequence set forth here: https://astrob.in/costym/0/)
