Nova Centauri

[gregbradley]

After seeing Rolf's superb Nova Centauri image I decided to image it whilst at my dark site over New Years.

TEC180Fluorite, PMX, SX Trius 694 LRGB 2 minute exposures.

You can see it appears to be a double star.

Greg, are the red bipolar jets part of the SNR? I've not seen this before.

Hmmm
Not sure what you've got there....the V1369 Cen nova is definitely a single star about 6 mag.

I don't know John. Its only in the red filter not in the others. It could be filter flare although I have never seen that before. All images were taken consecutively so conditions were identical.



Per this article Nova Centauri has a companion star:

Greg, astrometry.net thinks this image is centered at 14:42:39.340 -64:58:42.768 and the star at the center is Alpha Cir HD128898

Greg,
The nova Cen, like all the nova (not supernovae!) are binary systems.
They are spectroscopy binaries at the best, the companion would not be see with normal telescopes.

For what it's worth, I had similar flaring on the red filter when taking images of the nova in early January.

I'll dig out mine this arvo when I get home

I agree, Greg I think you are pointing off target.... Nova Cen is located at 13 54 47 -59 09 08

Oh dear did I miss it?



Thanks for that.



Yeah I doubt its a jet. It looks like filter flare from a bright star.



Possibly. I did centre using a finder scope so it could be off. Bugger.

I had a look at my subs - it looks like diffraction spikes on my image. And lousy processing on my part
