Heard about it on the spaceweather site from a mate and realising its well placed imaged it tonight.
Image is 4 x 5 mins at ISO 200 with the EOS Ra and 10 inch f5.6 newtonian.
Full sized view here

They have it as HD 162214
Glad I was able to get it, will try and image it on upcoming evenings to see the colour change and watch it fade.

Nice catch. I saw the communiqué via email. Was wondering if anyone imaged it. :thumbsup:

Good catch!
If you have a spectrograph or grating we need to get some spectra of this recurrent nova. Current spectra show the prominent hydrogen lines from alpha through to epsilon in the UV.
An ideal object for both low and high resolution instruments.

Thank you, thank you, thank you!!

This is something that I regularly monitor (several times in the last month), so I can hardly wait to have a look tonight.

Unfortunately, the weather has been rather ordinary and I have not monitored it or a few other possibilities (like t coronae borealis) for several days.

Great capture Scott, when you know what it is, an ordinary looking star takes on a whole nother perspective :thumbsup: Nice to see something other than M8 too... :scared: :rolleyes: :lol: Actually, was looking at M8 through the 12" dob up here at Eagleview last night, using my 30mm 80deg wide field eyepiece, could see the entire Bart Simpson's head with plenty of shapes and detail within, looked awesome under these dark transparent skies :thumbsup:

I'll come to Eagleview to image M8 but only if I can bring RB along. :thumbsup:

Would be great to suck in photons from such a truly dark and stable sky :)

On the Nova, little has changed over 24 hours, here is it last night, same scope and camera

So, I guess you could say there is "nothing nova" about it :P

"A spectrum shows the soul....."
There are daily changes in the emission spectrum. Dominated by the Balmer series of hydrogen.
One of the earliest spectra was obtained by my mate Jean-Bruno.

Any idea what magnitude it is tonight (12 Aug) guys?

Latest AAVSO data shows a magnitude around 6.0

I will photograph it again tonight to see if it is turning more red.

Ah ok Ken cheers, it was near "my" naked eye limit up here (Im 54 and wear dirty glasses :P) at Eagleview, so I was thinking Mag 6 - 6.5 :thumbsup:

Cheers

Took this om Aug 20. Its reddened a lot. Was really strikingly red when looking at it at 30x live view on camera display screen.

The very high H alpha emission is certainly contributing to the redness of the image.
