Hello,
we send our spectrum of the MAXI J1820+70. This spectrum is taken on 2018-07-07.0907.
The spectrum is a sum of 6 x 900 sec images with a Celesctron C14 f/11 + LHires III + 150 l/mm + CCD SBIG ST7XME at the Osservatorio Astronomico Margherita Hack, Firenze (OAMH).

We hope this spectrum will be useful to you.
