Here’s an animation of before and after the event: [https://www.astrobin.com/full/7jvafm/0/?mod=&real=](https://www.astrobin.com/full/7jvafm/0/?mod=&real=)
Coincidentally I imaged M101 on thursday night pre-supernova, so I conveniently had data from just about 24 hours before the event
When I heard the news, I pointed the telescope to the same area of the sky on Friday night and took a bunch of frames.
Processed both sets of subs to 2 images, then got those images stretched and looking about the same brightness, and crop size...Put them in blink and captured a movie off the screen, converted to an animated GIF.
Note the star is not blinking. This is flipping between two imaging sessions, captured about 24 hours apart.
The background is a little lumpy from in-town light pollution.
