UVEX by Shelyak in near IR

Postby Olivier GARDE » Thu Apr 15, 2021 4:37 pm

Here’s a Regulus spectrum taken with an ASI 183 MM pro and a 600 gr/mm grating in the near IR part of the spectrum to show the Paschen lines.

For the wavelength calibration, I used the same polynomial calibration as I used in the UV part.
The UVEX is very stable at all wavelength range for a given grating.
