A super widefield astrophoto I took in a bright & short moonless July night (2021). This is just 12 mins of unguided data! I used a reduced FSQ85-ED and a D180A. Can you spot the bright supernova Nova Cas 2021 below the star cluster M52? It was really bright that night and I couldn't resist and after the short imaging session I bought out my 100mm fluorite refractor and my widest 40mm eyepiece to observe it. The seeing was phenomenal that night.
