Supernova SN2011dh in M51

Friday morning I received an email from the ISN maillist about a possible supernova in M51. That same night I was able to observe the supernova at public observatory Bussloo with fellow observers Alex and Mendel. We used the observatories 30cm F/5 telescope with a 10mm Ethos (160x) to view the magnitude 14.1 supernova.
Supernova SN2011by in NGC 3972 (13.8) was also revisited.

Notwithstanding the mix of high temperatures and ‘grey’ nights (it doesn’t get really dark here this time of year) I caught the SN with my new William Optics GT 81 telescope:
WO GT 81mm, F/4.7 (f=478mm + 0.8x reducer), Canon EOS 40D, ISO800, 5 x 90 sec.
