Details:
This morning, a fellow amateur astronomer informed me of a new nova discovered March 18, 2021 in the constellation Cassiopeia. My immediate thought was that I just imaged a faint planetary nebula (KjPn 8) in Cassiopeia (despite being very low in the sky now after twilight) because I was so curious after another friend, Dr. Dan Good, recently sent me a beautiful H-alpha image of KjPn 8 he took in November 2020. So I wondered if I had fortuitously recorded the nova in my attempt to see KjPn 8 a few days ago! Sure enough, when I blinked my anemic 15-minute 100mm f/3.8 Vixen refractor (SBIG 11K CCD) H-alpha image taken on discovery day, March 18, 2021, against his deep H-alpha pre-nova Nov. 2020 image, Voila! And the nova appears quite bright in H-alpha light, not surprising considering the large Ha spike in a spectrum of this nova obtained March 22, 2021 by Dr. Adrian Jannetta of UK. Attached is my single annotated H-alpha image (taken at altitude 9 degrees) as well as a gif animation of my image blinked against Dr. Good's pre-nova H-alpha image.
And to think I was originally content with just barely recording KjPn 8!
