Steven
About your photo. Its great but are you sure the SN is the blue star on the right hand arm?
The reason I ask is that I photographed that galaxy on the 4th May 2008 and the blue star is in the right hand arm as shown by your photo.
See the antenae shot http://www.iceinspace.com.au/forum/s...hlight=antenae where I was testing out my new 127mm apo. The star is clearly there and also present in this image http://news.softpedia.com/newsImage/...er-to-Us-2.jpg

Sorry, I thought this was a recent supernova until I saw that it refered to one in 2007. My apologies to my unwitting mistake - never knew that the S/N was still around after all this time.

Thanks to Steve, Jase, Marcus, Allan, Leon, Ric, Rob, Alex and Clive for your comments.
Initially I had no idea there was a SN in the image. It was destined to a Photoshop deletion as I thought it was an artifact. However it looked too stellar like. It's nature was confirmed by it's presence in the R and G images.
I vaguely remembered someone commenting on a SN in this forum late last year so a bit of detective work using Google confirmed the blue star was the SN.
Very nice steve!
you have captured the tails very nicely...
Made me look back at my meager attempt in march and the SN is a bit brighter about the same brightness as the star just below it. Looks like its fading fast!
cheers
Magnificent Steven. The tail extensions are quite profound. I'm guessing you don't chase reflections in PS...
Jase,
If you're referring to those halos I find it quite difficult to remove in PS without the wrecking the star image. I find the best method (but by no means very effective) is to desaturate the halo.
Thanks for posting. Upon seeing this I looked back on an image of this object I took on 26th may, sure enough there appears the supernova. If it was discovered last year gee its been going for a long time now, I didnt think supernovas lasted that long

I wouldhave thought it would be over by now thats what made me think there was an error. Interestingly the blue star does NOT appear to be present in photos taken prior to 2007 (see attached). Therefore its very very slow to decrease its light curve and Wooo Hooo my first photo of a supernova!! Be interesting to get another photo at Astrofest but this time deeper.

Congratulations Allan.
This is my second SN image. The first one was a SN in NGC 7424. Unfortunately due to camera issues at the time, the colour balance was all wrong and the SN came out red.
