Before and after:

I was lucky to have captured the same are of the sky on April 24, 2022, and after the discovery was announced, I took an image of the same frame on the first available clear night at home on April 27, 2022.
The image below shows the before and after comparison. These frames (58x120s) were taken with my backyard setup at a FL=516mm and f/2.2.
