VY Scl spectrum by using a 8-inch telescope

A coordinated spectral observation with Olivier on VY Scl  by using a modest 8-inch Nexton telescope and a Star'Ex spectrograph (3D-printing). From France at the elevation of 14° only above horizon. See the result on the link given by Olivier.

Also, you can find spectra of V794 All and V704 And.
