Hello,

Among other jobs, I'm working with this low-resolution spectrograph. My intention is to finish it by mid-November,
and make the first test then.

I'm going to send more information in the coming weeks.

Cheers, Joan.

Hello,

You can see that whereas Pi Aqr, as the other Be stars, shows stable % Polarization and Theta Angle levels, P Cyg has oscillating values on their ones.

Cheers, J.Guarro.

Bonjour François,

It's seems that all is "calm" at T CrB.

Cheers, Joan.

Hello James,

Without any doubt, that is a great step, so you can observe a lot of targets with very high resolution now.

In this way, I would say to you some little suggestions about your eShel; if I were you, I would try to improve the three points centered as your Check2 image shows. You can ...

Hi James,

Something hasn't worked, but your writing doesn't show the images, please could you try to mend it.

Many thanks, Joan.

Hello,

This is what I could take last night from Pallas, it is on the boundary to take "comfortable" observations.

This is the result of 4 x 800 sec integration séries, for 0, 22,5, 45, and 67,5 degrees positions, 12800 seconds in total.

Regards, J. Guarro.

Hello,

A star studied spectroscopically for many years is VV Cep.

Its spectropolarimetry data says something, one only needs to understand why.

Cheers, J. Guarro.

Hello,

These are two graphics of a T CrB polarimetric observation.

I hope that you enjoy that.

Cheers, J. Guarro.

Hello,

I present to you the Linx, a revised low-resolution spectrograph.

The goal is to achieve a complementary tool for the NOU_T scale, since with it
it would be possible to observe objects around the 14th visual magnitude.

I hope that you like it.

I'm going to say in next few weeks how things ...

Hello,

Despite the weather, I can observe from time to time.

You can see these changes of intensity in V CVn.

Cheers, J. Guarro.
