BF Cygni

Excellent night tonight, with very good seeing (well, for the site; estimated around 3") and sky magnitude (with SQM) around 20.6.

I started with some known friends such as VV Cep and P Cygni and switched to a star of interest at the moment, the primary target scheduled for the coming OHP spectroscopy workshop: BF Cygni. This is a classical symbiotic binary star but the shape of some emission line (H beta for exemple) has the signature of strong jets emitted from the system.

Here is the observatory computer screen copy showing the guiding image, the spectrum (H alpha is very strong), the two CCD control (acquisition camera & guiding camera), the skymap area (around BF Cygni) and the telescope control:

Here is a view inside the dome, telescope pointed toward the target:

And the guiding camera long exposure (Atik Titan, 10sec) to see the field of view around BF Cygni:
