One of the brightest nova in recent history, 6mag is now visible in Delphinus. Here's you chance to record the varying brightness and collect useful spectra of an amazing object!! http://www.cbat.eps.

Many thanks for the post, I'll take a look as soon as I have the opportunity. It takes me back to the 70s and another nova Del, I think it was designated HR? Anyway, back in those days I used to do

Drifting cloud last night Thursday Aug 22 after dusk but got a quick shot via piggybacked 1100d and est mag at m5.5 against circled star and Sloan DSS. Perhaps more importantly [for me!] my 5th spect

Congrats Nytecam, that is a very interesting series of spectra, moving from mainly thermal continuum radiation, to more an more line emission from ionized gas.

Excuse my ignorance but did you deduce this from the more pronounced spikes in the spectrum lines from 16th to 20th August?

Yes. Pure thermal (or black-body) radiation is a continuum yielding a smooth curve as a spectrum. Ionized gas produces strong emission lines showing up as spikes in the spectrum

Thanks for that.

Just got it tonight in my 15x50is binos. Right on the limit of visibility, needed averted vision to spot it. Similar to other reports, I put it a little dimmer than the nearby mag 9.0 star, so around 9.2 ish

Which bins did you use?

Did not get to see it yesterday, might have a bright spell tonight, and I will get out the 15x70s or the 80mm frac

My Canon 15x50is binos. As said, I think I generally find around 9.3 to 9.5 is limiting mag underused skies at home.

Definitely seems to be a big bino/small scope object now but great to have followed it all the way down from mag 4.5 (if I remember correctly).

My pic below in 20s exp [inset 3s exp to show colour] from last night.  My est =m10.2 eg a ghost of its former self at outburst :police:

Is it really that colour!? Wow. Also, what is that "extra" star above right of centre in the inset image?
