2021o3 20220516 2030 aaletti

yesterday evening the sky was very clear despite the full moon, so finally i have observed the comet or the debris of C/2021 O3
with 8" f4 Sch-New Telescope, Ccd without filter at 1,64 x  Pixel and 30 minutes of total exposures. 
The coma was very diffuse but at least 60 seconds wide and a very weak central condensation; 
With a large aperture (10 Pixel) i have measured +15,7 magnitude.
