Description

This is the final 18-panel mosaic that targets almost the entire Virgo Galaxy Cluster--from M49 to M85. We froze our globular clusters off for 19 nights between February 19, 2021 and April 11, 2021. Processing it has been a challenge, to say the least. The original source image is 22,234 X 29,247 pixels, but we had to downsample it to 12,544 X 16,500 to be able to post it here. Add to that the fact that it's in jpeg form, and I'm not sure how nice it will look here.

While we were shooting this mosaic with the small WO Z61 refractor, we were taking individual shots of all the Messier galaxies--16 of them--in the cluster with the 1100 EdgeHD. Those shots will follow in the coming days.
