Bonsoir Christian,

Many thanks for your explanations, as you said we really need to attract new spectroscopy 
observers and that it's a good way to achieve it.

I hope and wish that you reach this challenge and you'll be compensated for your time and efforts.

Cheers, Joan.

Bonjour Christian, Fortunately we can read another very complete master class from you, your extended and interesting exposition about abundance and different ways and update technology and software. Many thanks for your effort, because you had spent a lot of time on this explained job. In my opinio...

Chiao Umberto,

Nice observation !! You're one of the few people who shows your results here, so it seems that all has stopped.
Congratulations !! I hope that it encourages people to observe and expose their outcomes here again.

Un forte abbraccio, Joan.

Hello all,

GK Per is in the boundary of my equipment detection, but it's possible that despite the noise the graphic would still be useful.

Cheers, Joan Guarro.

Hello at all, It is known that more every time, unfortunately, the H Alpha line plays a more secondary role in Astrophysical studies, the scientific stars analyzers are focusing on the other physical elements for their conclusions about stars evolution. You can deduce that the high resolution H Alph...

Hello, In this Forum at " Outbursts, Alerts, Monitoring " section, you can see some results of the current observational campaign of GK Per Cataclysmic Star. Every observation in low or high resolution about this current fenomena is very important, could you help understand it with your ob...

Hello everyone,

These are my first results about this interesting star.

Cheers, J. Guarro.

Hello,

As a first 2023 spectrum I made a test to know where the boundary South of Piera Observatory is. I am glad to show it here, and wish you the best for this new year 2023 again.

Regards, Joan Guarro.

Hello,

Today the last one of the year I would say Goodbye to it with these two symbiotic star
graphics.

That would be a greeting for their observers and a reminder for the other ones, these types of stars would be really good targets for next year..

I wish all of you a Happy 2023 !!

Joan.

Hi Robin, As you said, the perfect spectrograph doesn't exist, and I'm afraid that an echelle isn't the best tool for taking a good calibration flux, in my opinion, using a low resolution spectrograph takes very useful data for it and more easily. One can see that almost all studies using echelles, ...
