Shelyak UVEX Motorized (ES0034)

Shelyak UVEX Motorized 

The UVEX is a Czerny-Turner spectrograph called “crossed” and optimized for wavelengths ranging from near UV (<350nm) to near IR (1µm).
It is particularly dedicated to be used on Ritchey-Chretien telescopes with a diameter up to 12 or 14 inches (at F/d 8)

The uvex comes with a 600 l/mm grating blazed at 500nm as well as an adapter ring for ZWO cameras (other rings for QHY and ATIK cameras are also available as an option).

The UVEX

• The UVEX is a so-called “crossed” Czerny-Turner spectrograph optimized for wavelengths ranging from near UV (<350nm) to near IR (1µm).
• It is particularly dedicated to be used on Ritchey-Chretien type telescopes with a diameter up to 12 or 14 inches (at F/d 8)
• The UVEX comes with 600 tr/mm blazed @ 500nm grating as well as an adapter ring for ZWO cameras (other rings for QHY and ATIK cameras are also available as an option).

Mototrization :

• Motorized UVEX allows you to choose the central wavelength observed and to adjust the focusing of the spectroscope.
• Control of the integrated calibration module: The motorization integrates the control of the calibration module (function equivalent to the SPOX module). It is therefore easy to make your images of black, flats and calibration, remotely.
• The UVEX motorization module is accompanied by a new version of the DEMETRA software:
  – Calibration “by readjustment”. We establish once and for all the law of dispersion, and we can readjust it on a well identified line. This is useful for covering all areas from UV to IR, when the reference lines are few.
  – Motors module management,
  – Image sequences, to link several series of images,
  – Consideration of CMOS cameras (by the CMED correction step).

The spectrograph slit has 5 positions that can easily be changed using a Phillips screwdriver (delivered with the UVEX). Several slit widths are thus available: 25 μm, 50 μm, 100 μm, 300 μm and a hole of 25 μm. Other slits are available as an option and Alpy slits are compatible with UVEX.

Recommandation :

We recommend to use an ZWO ASI 183MM pro camera with the UVEX spectrograph
