    Not certain as to which forum this is best placed, and this is my first post as a new member of BAA. Correct me please if need be.

    Monday night (26 Nov. 2018) I had the opportunity to photograph the new supernova in M77, SN2018icv. The galaxy is difficult to photograph, due to its small angular size, but we were not out to take a detailed image of Ha structures, but to capture the star while still near peak 13.5, up from normal 19! Location Västerås, Sweden. ODK 16 with a Canon modded 6D. 69*30 seconds, Baader UHC-S filter.

    Hello James. I am a fan of imaging transients and noticed this one a few days ago on David Bishop’s website. IMHO it certainly is worth flagging this on the forum – as a (visible) PSN or SN in a Messier object does not occur that frequently. Great image! The weather where I am is atrocious. David

    Welcome aboard!  I’m a newbie on the forums and only re-joined the BAA a few months ago after a 30-year hiatus.

    Your image looks pretty impressive to me.  Much better than I could produce given my (present) incompetence at driving my newly acquired equipment.

    Hi James

    That is nice image of SN2018ivc  I took a spectrum on 24th and found it quite tricky to separate it from the galaxy core.  Here is what it looked like in the spectrograph guider, and a low resolution spectrum showing H alpha emission at the galaxy redshift, characteristic of a core collapse supernova (It was already too low for me when it was announced the night before so I was beaten to a classification for this one by professional teams in Japan who got there a few hours before me)

    Cheers

    Robin

    Hi James,

    Very nicely captured. Pop a copy on the Community page too? Good to see it in colour.

    Thanks everyone, I have posted on the Community page, as requested. Cloudy here, or we would have tried to follow this with more images. I really appreciated the spectral image. Am still learning about this stuff!
