Two evening supernovae

And now for something a little different

Two of the brighter supernovae in the sky, both Type II, are in the evening sky just now:

ASASSN-14ha is somewhere near mag. 15.0 and in the Spanish Dancer, NGC1566, 38 million light-years away in Dorado, photogenic, but challenging to resolve in my equipment. 20 minutes of 5-minute subs, 150mm f/5 Newt, EOS60D at ISO640. It is inconveniently located between a foreground star and the bright Seyfert nucleus. Larger version here.

SN2014cx was a similar brightness in the irregular spiral NGC337, 60 million light-years away in Cetus, mag. 14.9 on the Bright Supernovae page. The SN is on the upper-left side of the galaxy. The image is a stack of 6 x 5-minute subs, but imaging into the Sydney light dome from my home and only the brighter parts of the galaxy came out through lots of red smoke/dust haze. The big dim spiral NGC337A out of the crop but very nearby was just about invisible in the stack (a few bright knots, might make a good dark-sky target).

Very well captured Andy! I understand NGC1566 is a difficult one. You have it separated nicely.

Thanks guys! It's fun to try something different, and also something that changes in the deep sky. But I'd love to see someone with better equipment (or a darker sky than mine) go after NGC1566 just now, it's such a photogenic spiral.
