Shelyak UVEX
UVEX is a cross Czerny-Turner spectrograph optimized for wavelengths from near UV (<400nm) to near IR (1µm).
We recommend to use an ASI 183MM pro camera with the UVEX spectrograph
In this article you will find a lot of additional information about UVEX.
It’s particularly dedicated to be used on Ritchey-Chretien type telescopes with a diameter up to 12 or 14 inches (at F/8)
The settings are precise and easily accessible:
- A multi-turn knob adjusts the focus of the M2 internal mirror precisely.
- An index os used to adjust the wavelength center of the spectrum on the camera sensor. A vernier (available for each type of grating) makes it possible to precisely position the grating at the desired wavelength.
The UVEX is delivered with a 600 gr/mm grating blazed at 500nm as well as adapter ring for ZWO cameras (others rings for QHY and ATIK cameras are also available in option).
The spectrograph slit has 5 positions that can be easily changed using a Phillips screwdriver (supplied with the UVEX). The slit position are for 25 µm, 50 µm, 100µm, 300 µm and a hole of 25µm. Other slits are available as an option and Alpy slits are compatible with UVEX.
