Hello everyone, thanks to Jaroslav for giving us this new and exciting challenge. From his list I decided to treat the simplest Gaia object, Gaia10dxh, and acquired some spectra yesterday 20 October from my observatory located in the light pollution of a small town. After a comparison with the star ...

Hallo everybody, here my simply comparison at low resolution made using alpy600 not flux calibratied. I can see an evolution in the spectrum noting an incresing of expansion gas from around 900km/s to 1600 km/s. It would be very interesting to continue acquiring spectra to evaluate the evolution but...

Hallo everybody, here my comparison at low resolution of this Nova taken from 3800A to 7900A. At low resolution I noticed an incrase of the basic lines and a splitting of the h alpha line. I also noticed an incrise of the OI (?) line at the extreme end of the spectrum. Would it be possible an overla...

Hallo everybody, here my last spectrum of ASASSN-19aad taken yesterday evening. The profile evolved over the days showing a very broad and pronounced H Alpha emission line. In my low resolution spectrum we can see also weak emission lines as FeII (5018.4 A, 5169 A, 6248 A, 6456 A) and maybe a CII li...

Hallo everybody, here my last spectra compared with the 4th July consistent with those reported at low resolution. Since we use a Newton telescope togheter with an Alpy setup, i am strong interest to know more information about calibration spectra and problems about the weight of the cameras and the...

Hallo everybody,
these are my first low resolution spectrum here on aras group. I did theme using an alpy600 coupled with a 200 mm newton telescope. I attached the last spectrum of AG Dra made this night and a comparison made to show some changes in He and O VI spectrum lines

Hallo to all ARAS members, I am Paolo Cazzato, I live close to Lecce and I do my observing from the polluted sky of Salento extreme south of Italy. I have been interested in astronomy since 1997 when I was fascinated from the Hale Bopp comet. Since then I have been using my small telescopes for obse...
