Given the rather good weather in my part, I have developed two other spectra of the stars HD 91120 and HD 79066. I place the two profiles for sharing.

To: Antonino,

Do you have any spectra below 4000A to show? So far your spectra looks great, but it would be nice to see
how far towards the UV you can go with your set-up.......

I'm doing other spectra in this wavelength range. I'm not sure that the Relco lamps I use allow me to calibrate even on blue. Soon I will try.

Also from the balcony of the house I observed the star HD76868, placed the spectral profile.

In these difficult times, the only entertainment we can afford is observation. The last spectrum that I have elaborated is the star HD89884. It is, as always, a Be star whose obtained profile has an R = 807 and a dispersion of about 4.16 A / pixel. Simbad gives for this star a magnitude V = 7.13. While the spectral class turns out to be a B5III, therefore a giant of class B. It is interesting to note the double absorption on the line of the Habeta that the harvested instrument.

Hi everyone. I tried to calculate the limiting magnitude of my instrumentation with UVEX. I have a problem with the version of ISIS V5.9.4 because it does not recognize me some commands of the "command line". How can I solve?
Thank you all
