Details:
Nova V1405 cas was shining at about mag 7.4 from shortly after its March 2021 discover until May 5/6 when it had an outburst that peaked at mag 5.4 around May 11. This made it the brightest nova since 2013. Shortly after it declined in magnitude back to mag 7.4 and visibly reddened. This shows the outburst at mag 5.4 on May 11 and the decline to 7.4 on May 21. This pair of images was captured with the T68 telescope of iTelescope in Mayhill NM using a 120 sec exposure.
