Nova Cassiopeia 2021(V1405 Cas)

A quick ~20 minutes of integration before the clouds rolled in.

You can see Nova Cassiopeia 2021(V1405 Cas) in the image along with the Bubble Nebula and M52, an open cluster.

There’s a ton of noise due to the lack of integration time. The nebulousity of the Bubble Nebula is also subdued as a result.
