Here's a new spectrum of T CrB with my little 72mm refractor. (A bit of a challenge ) In red, for comparison, a spectrum from a year ago.
Cheers,
Guillaume

Re: GK Per Outburst
Hi Christophe,
I don't have much time available and the weather is really bad right now
However, I will try to do some more GK Per spectra in February !
And yes, I sent my spectra to the aras database
Clear skies

Top ce spectre Hubert ! Merci pour le partage.
J'espère aussi pouvoir la tenter prochainement, quand la météo sera un peu moins capricieuse
Pour le guidage c'est quoi le soft en question ?

Re: Changes is Ups Sgr spectrum ?
Hi all,
The profile of ups Sgr has changed significantly in a few days
Here the comparison of two spectra (heliocentric correction applied). All lines are shifted! Probably the doppler effect of the binary system...

Re: Changes is Ups Sgr spectrum ?
Hi Robin & Hugh,
This "continuum" between the blue wing and the right wing of this pseudo P Cygni profile really caught my attention during the acquisition. It's indeed unusual ! Thanks for the link Robin, I'll go read that.
Cheers,
G
