Nova Mon come to a faint object (near V=12), but easy with a LISA spectrograph:
The spectrum is taken during nearly full moon (a natural pollution) from Toulouse.
Here the 2D spectrum with numerous Fraunhofer lines + city pollution:
and now after removing the sky:
The interest of spectra image processing

Well done. Too far north for me.
You have to cope with so much light pollution. I just don't have that problem.

Here's a spectra taken last night at OHP with a C14 and LISA (23u slit) with very poor weather conditions.

Très bon Olivier.
Je veux bien que tu m'envoies le fit pour le rajouter au tableau des observations.

Image of Nova Mon 2012 taken with Alpy 600 guiding camera (here an Atik314L+)
the Marrch 31 at V=12.5:
and the spectrum for the date:
The telescope is a 8-inch newton (Takahashi CN212).
