Description

V1405 Cas is a nova (“new” star) that was spotted in Cassiopeia by Yuji Nakamura on March 18, 2021. I imaged it last night with just 8 2-minute subs, between tree branches and overhead wires, given how low on the horizon Cassiopeia is in the evening. After processing the data, I registered the resulting image with a pre-nova picture of the same area I had obtained last summer (the region is home to popular deep-sky target like M52 and the Bubble Nebula), and I produced a video by blinking the two images, here converted to the GIF format.
