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 ...

Re: Nova Sgr 2021 (a)
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 ...

Re: Nova Sgr 2021b - Second nova of the year in Sgr
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 ...

Re: ASASSN-19aad, possible nova
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 ...

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 ...

Re: AG Dra brightening
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, presentation
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 ...
