Hello all,

send results to last nigth, although I have some problems with the software I think NOU_T it's ready for work.

It's working well in the ordres 56/55 to 26, from 3910/3980 to 8670 Angstroms. I was very worry with his mechanical stabilty but I'm calm about it when I've seen desplacements = 0 in X and Y in the ccd image after the tour for these four stars.

The big dinamic rang it's due that using mirrors instead of achromatic lenses, with restes of chromatic aberration in them, and the Nikor objective 85mm. F/1.8 it has a aspheric lens and one compromissed focus between all his Orders. I don't want the best focus only for concret Orders, if not, the best relation between all of them.

I see that NOU_T it's better than the MUSSOL and LINX it has bigger dinamic rang and without optical fiber nor the fiber agitator indispensable for relation focals more longer than F/4 .

NOU_T it's arrived to stays here.( If I don't wrong ).

See you, Joan.

Nice results Joan!

Is this Nou_T Echelle significantly cheaper than the other commercial ones?
Looks like good R into 9000A.

Your post reminds me to shoot VV Cep with the IR LISA when I get the chance.

Hello all,

Although that some software problems the NIGHT it's ready for work. To fact I've started work seriously with it.

The mechanical part comportment it's excellent between the tour of these there three stars the maps pixels CCD variations are X0= and Y=1.

I think it's important in these graphics is can detect the calcium triplet at same time. I show you three examples.

Regards, Joan.

Hi Joan,

Very impressive work and results. Tim's design is really excellent too.

As I don't feel able to build the box, would it be possible to acquire (at least) the box and what will be the prize?

All the best

François

Bonsoir François,

Many thanks for your interest.

Who can build the mechanical NOU_T parts with the drilled flat mirror incluided is Toni Jové,
tonijove@outlook.com, he wants to do it. I can help to you all with all necessary advice for mount and collimate the optical components. It's and easy and instructive, ( and I think necessary ), job.

I can send an actualized list to optical elements and different combinations.

Bien amicalement, Joan.
