Hello everyone. Here is my go at supernova SN2024ggi in NGC 3621. About 2hours worth. DSS, Siril, Gimp. Quattro 250 F4 newtonian, unmodded canon 600D. Thanks to Dunk for the inspiration from his image.
Cheers,Rob
Thanks Glen and Steve(Bodon) for your encouragement.
Joel , well done with your image.
Thanks Paul and Steve(Astroviking) for your comments. It is a worthwhile target and easy to get. You can see the supernova in each individual image.
Thanks Dunk. Your image was an excellent inspiration. There was a bit more detail in the galaxy before I had to reduce it to the 200KB to get it on IIS. Adding the indicator line took another 60KB of data off. On my original photo in tif format I can see a bit more of the outer arms.
I probably can’t get much more of the outer arms with my camera in the city. But ISS members with astro cameras may be able to do a fair bit better.
The supernova itself is a pleasing sky-blue colour. I can make this out in my original photo and I will attach another 200k image here without the indicator line to see if it shows up. I can also see this blue colour in Dunk’s image in the Deep Space section.
I think this sky-blue colour would make this supernova a good target for those who can do spectroscopy and I would be keen to see their results.
It’s an interesting galaxy , being very flat with little central bulge. It apparently has 3 black holes in the centre.
I read somewhere that a Supernova this close (23 million light years!) only comes up about once a decade.
That second image is great - I can see plenty of detail in the galaxy and the colours look good to me.
I hope you don't mind me piggybacking onto your thread - it didn't seem worthwhile to create another thread.
I processed all 5 test frames (a total of 3 minutes and 5 seconds) for the hell of it. I was very pleasantly surprised to get something I can be mostly happy with. Sure, there's zero detail in the galaxy (being just a brown-ish smudge), but the SN came out quite clear. (Not much colour, though.)
Hopefully the cloud gods take pity on us Melbourne dwellers and we can see the skies again soon...
That's great Steve. Definitely worth you getting more data. Apparently this is a young type2 SN. Definitely worthwhile someone here to do spectroscopy . Rob
NGC 3261 was part of a visual Supernova search I conducted
with both my 8" and 16" scopes from Cambroon observatory
Sunshine Coast Queensland for quite a few years.
I have observed it many times.
The search was designed and coordinated by
Dr Ian Wilson a former professional Astronomer, who
had a theory as to what galaxies would be liable to have
a certain type of Supernova.
Even though his sample was small his theory was proven
to be correct.
Ian Wilson has passed on now but I bet he would have been
chuffed to see another galaxy in his survey has had another
Supernova added to his list.
RIP Ian.
Great image by the way.
Cheers
Good shots, Steve Peter and Glen. Thanks for your insights astroron. I haven't look lately but when I last imaged this, it didn't seem to have dimmed yet. Worth another look when this rain and cloud finally goes, Rob.
