For high resolution spectroscopic observations, the C11 + LHiResIII with 2400 l/mm grating obtained several spectra of the stars: kap Dra and variable stars: RR Lyr and X Cyg.
several stars are observed with high res. spectrograph LHiResIII: gam Cas, eps Cas, phi Per, V442 And and vriable star X Cyg.
with disturbing moonlight several comets are observed from BRIXIIS-I observatory and spectroscopic observations with BRIXIIS-II observatory. comets which are observed are: 21P, 29P, 37P, 38P, 59P, 64P, 66P, 78P, 130P, 198P, C/2017 K2, C/2017 K4, … Read more
With remote telescope, i observed comet 46P/WIRTANEN with remote telescope from New-Mexico.
After a first attempt with the LHiResII spectrograph i did again several spectroscopic observations of Be stars: 14 Lac, 28 Cygni and variable star X Cygni. The slit was set on 19 µm and a … Read more
As first light i choose Cepheïde variable star X Cygni, a star with magnitude between 6.4 and 7.5.
