Dear Joan,

Thank you very much for your reply with the graph containing now also a wavelength scale.
Whenever you would plan to sell your NOU_T, I would be interested!!

All the best

Have a nice day

Tony

Hello,

The spring and summer stars are coming again, these pictures show Del Sco results with the definitive characteristics of the Piera Observatory equipment, in my opinion it's the most effective and agile combination that, - into my  possibilities-, I’ve  been able to do.

Cheers, J.Guarro.

Dear Joan,
the Halpha spectrum would be very helpful to determine the radial velocity during the periastron passage, the campaign of Anatoly Miroshnichenko.
Please send me your spectrum for evaluation of this parameter.

Ernst

Hallo Ernst,

I would want to send it tonight, and ask you if you need to at the same time always a second observation more exposed fro Helium 6678 measurements.

I'll write you later, Joan.

Hello,
That is the symbiotic RW Hya, from Piera last night.
Cheers, J.Guarro.

Hello,

You can see here another example of symbiotic star and details of its Calcium Triplet region.

Cheers, J.Guarro.

Hello,

I leave here a T CrB graphic, from SMM Remote Observatory and a ten days blue zone comparison, made through two different observatories and NOU_T echelles.

You know that getting good results on the blue zone at R = 9000 from a 9 magnitude red star is not always easy, this justifies the noise.

Regards, J.Guarro.

Hello,

Sure that you know that a new Jonathan Labadie-Barzt's Be stars campaign has started.

You can see both samples here.

Cheers, J. Guarro.

Hello,

The optimum and indiscutible very good results obtained by the NOU_T echelle in R=9000 with its very long coberture of wavelength range , also with an unusual weak noise, have stimulated me to attempt a new aim, so it's to obtain photometry V and spectroscopic simultaneous.

So I will try to take photometry, with an old Asahi-Pentax Takumar F=300mm. f/4 plus an ATIK 460EX CCD, I believe that they would work well for
8 to 11 magnitude stars, with more brilliant stars it's possible the photometry needs more extensive field pictures for find stars with similar magnitude, it would be reach using 135mm. and 85 mm. objectives.

You can see here the first preparation steps.

Regards, Joan Guarro.

Hello,

You can see here another example about the good NOU_T echelle performance with this CI Cyg graphic and also its field picture.

For photometric tests it only lacks the photometry V filter, it suffers a delivery delay due at holidays time.

Regards, Joan Guarro.
