New UVEX by Shelyak : first light

Here's the prototype of the UVEX by Shelyak, all metal parts.
Image

On this UVEX is fixed :
- The ALPY 600 auto guiding module
- The ALPY 600 calibration module
- A CMOS sensor for science image (ASI 183 MM Pro)
- A CMOS sensor for auto guiding (ASI 174 mini)

With this UVEX, it's very easy to change the grating without opening the spectrograph. You have just to unscrew a large button and change the grating support.

You can have different grating support and change it quickly

Image

For the first light, the UVEX is put on a RC12 at f/8

Image

And the first spectrum on Vega, 21 exposures of 1/2s each.

More to come and some results with an article on the Shelyak website, available soon...

Super nouvelle !
Le visuel des pièces donne l'eau à la bouche. Vivement la suite !
Merci !

Looks good! Hope we can get custom gratings like Christian did in his prototype to work
with Shelyak Uvex; like the Thorlab 300 l/mm blazed at 1 micron!

Wonder if we can buy it without the calibration&guide module, since I already have an Alpy600 with these.

Hi James,
Of course, the UVEX will be offered alone and can be completed with a autoguiding or calibration module and with several types of grattings.
shelyak is also developing a motorization for the focusing and the wavelength range to be able to remote control the UVEX.

Excellente nouvelle!

Y a t-il une idée de la date de commercialisation ?

Bonne continuation

I had best place a pre-order Olivier - looks like quite an instrument

Peter Velez: "I had best place a pre-order Olivier - looks like quite an instrument"

I had that idea too, but my sudden acquisition of an eShel may put this off financially for awhile!
I may retrofit my lhiresIII for UV with the modified Atik414ex camera; modified with Quartz window for better UV penetration.

I totally get it James - its not a cheap hobby. As my favourite local astro shop owner used to tell me, owning a boat or a racehorse is a much more dangerous pastime.

Are you able to share the details of the replacement sensor window with me? I have looked on the Thorlabs website and can't work out what I need for the Atik 460EX. If I do end up with a UVEX (as I hope), some more sensitivity in the UV would be a bonus.
