Hello,
This is T CrB on yesterday night.
The intensity of some lines changed in the violet, from the preceddent graphic.
Cheers, Joan.

Re: Nova Ser 2025
Hello,
After a lot of cloudy days I could observe Nova Ser 2025 yesterday night. It was on the boundary of SMM remote equipment,
but I have been able to reach this graphics by a NOU_T echelle.
Cheers, J. Guarro.

Re: First light
Hi Tom,
Bold design!
Are you using a Barlow lens? It seems that Alpy can work to F/5.5 approximately.
So you if you are using your 50cm telescope at F/4, you are losing a lot of light.
It's the same as if your telescope has only 40 cm in diameter, am I wrong?
Cheers, Joan.

MENDING AN OLD DOME
Hello to all,
As all of you can see in these pictures, today morning was a special moment at the Piera Observatory, we applied
a circular wall supplement in the dome number one that I made 45 years ago, this is another step in its improvement
before putting the old 406 mm diameter SC telescope ...

Hello,
You can see a reference star HD103287 and the variable V CVn observations, and the interesting views of
comparing their spectrum and polarization.
Cheers, J. Guarro.

Re: POLARIMETER DEVICE PROJECT
Hello,
From the village Horta de Sant Joan, a possible good place for observing the 2026 total solar eclipse,
I sent you these pictures from the last few days.
You can see the Mars Theta angle variations. And also, the Polarimetric software allows the
Instrumental Theta Error to be subtracted ...

Re: POLARIMETER DEVICE PROJECT
Hello,
Planets and asteroids spectropolarimetry observations are very useful if one wants to tune the Theta Angle,
that is the reason that I observed Mars on this last 12th.
The provisional found values indicated that TheGiver gives -2.5º, ( 17º), off of the Mars theoretical Theta Angle, (19.5º ...
