I haven't tried that faint yet.
Tonight I'm taking spectra of the new nova in oph PNV J17395600-2447420
The main hassle is a lack of guide stars. I'm having to use a 3 sec exposure for the guide camera.
It certainly looks like a nova with a wide Ha line measuring a FWHM of 2580km/s
I need to complete the calibration files before I'm certain though.
