Some spectra with the Whoppshel R=30000

Post by Olivier GARDE »

Some results with the Whoppshel spectrographe : R=30000.
During this observation, the sky transparency was not very good (some cirus clouds)

This spectrograph is dedicated for telescope with large diameter (>=60cm) but we can still obtain some results with smaller telescopes like a 400mm in diameter.

The limite magnitude with this telescope is about 6 (depend of course of the target type : lines in emission or not, the observation site, the sky quality, etc...)

I use an ATIK 460ex CCD in bin 1x1.

Very noisy, but with a résolution of 30000

This spectrograph is very stable with wavelength calibration and very acurency

And a merge spectrum of Vega from order #46 to #87 (spectral range from 3920 to 7510 Å)

H Alpha line on Gam cas compare with other echelle spectrum (eshel R=110000)

Telurics lines are deeper than with an eShel
