comet and spectroscopic observations on 8 june 2019

After some technical problems with the PC of the BRIXIIS-I observatory i could finally start with imaging on about 23u50 local time with comet observations: comets which are observed are: 68P/KLEMOLA, 123P/WEST-HARTLEY, C/2016 R2 (PANSTARRS), C/2019 D1 (FLEWELLING)  , C/2019 G1 (PANSTARRS) , C/2019 F1 (ATLAS-AFRICANO). With BRIXIIS-II observatory, i could obtain some high resolution spectra of Be-stars and var.stars with the C11 and LHiResIII spectrograph:  V357 Lac, HD 193182, gam Cas, omi And.

spectroscopic observations on 6 june 2019

I want to start to obtain spectra of variable stars for AAVSO. Since a couple of months AAVSO have  opened a  spectrum database.  As kind of verification AAVSO asked as first spectrum a spectrum of a star which they call a ‘standard star’ . So i took 2 stars from the list mu UMa and eta Boo. Also a spectrum of ALTAIR for the instrument response.  Later i could also obtain 2 spectra of Be-stars: 28 Cyg and HD 194335.

spectroscopic and comet observations on 25 may 2019

During a short period of clear sky i opened the 2 observatories , 1 for comet Observations and second for spectroscopic observations of Be-stars. I could start about 23:00 local time (this period of the year are the nights very short): comets that are observed are: 123P, 149P, C/2017 K2, C/2016 R2. After about 1.5 hour, clouds where coming in i must interrupt the observations.  Be-stars which are observed are: PHECDA, CQ Uma, HD 175863. (with LHiResIII and 2400 l/mm grating – R = +/- 14500)
