Nova Cas-2021


Nova Cas-2021

Nova Cas-2021
I had taken the Bubble nebula last Spring and just at the edge of the image was the star that became Nova Cas-2021. I captured an image of the same field last month... and here you go!
Both images are Stellina's JPEG. I used Affinity Photo to remove the noise and bring their luminosity to the same level (because the two images had not at all the same number of expositions).
