another supernova - in Cancer

[nytecam]

Tonight's shot at dusk in increasing haze of supernova in NGC 2554 in Cancer - unlike the SN in M65, this has brightened since discovery in March to current ~m15.4 ;-)

That's a good capture, it looks bright compared to the galaxy core but what perplexes me is how the **** did Herschel see 2554 in 1785?? I wonder what telescope (visually) would be required today from where ever Herschel saw it?

Just did some checking... he had 19" and 48" reflectors!

I don't believe they would have been anywhere near the standard of modern reflectors though. Herschel was still using speculum metal for mirrors, wasn't he?

Quite right James & here it is :-

Wow, which one is that?

Thanks Richard - did better last night [without looking through thin cloud!] as below

Is that colour difference between the core and the SN real?

Yes very nice capture
