I took a spectrum of gam Cas for HeI emission @ 6678 Å. with the C11 and LHiResIII in hijgh resolution.
several comets are observed during this shorts night of the year: 21P, C/2015 O1, C/2016 N4, C/2017 M4, C/2017 S3, C/2018 C2. Also with the C11 + L200 spectrograph where Be-stars observed for the H-alpha … Read more
During a clear night of 20/21 i did observations of some comets and observations of possible comet menioned on the PCCP (magnitude 19.7): comets which are observed are: 21P, C/2015 O1, C/2016 N4, C/2017 M4, … Read more
Comet P/2018 L4 was discovered by R.Wainscoat and found on images taken on June 8.5 UT with the 1.8-m Pan-STARRS1 Ritchey-Chretien telescope at Haleakala . This object was also observed by myself with my 0.4-m f/3.8 … Read more
Comet observations via BRIXIIS-I observatory in night of 18/19 june. Comets which are observed are: 21P, C/2014 OE4, C/2015 O1, C/2016 N4, C/2017 K2, C/2017 M4 and C/2018 C2. spectroscopic observations are obtained with BRIXIIS-II observatory … Read more
During the night of 13/14 june, several spectroscopic observations are obtained with the C11 + L200 spectroscope with 1800 l/mm grating. Observed stars are: P-Cygni, gam Casseopeia, QR Vulpecula
H-alpha detail, high resolutions spectroscopic observations with L200 spectrograph and 1800 l/mm grating (R > 10000) are made in the evening/night of 6/7 june: 66 Ophiuchi , HD 202904 and also VV Cep (not a Be-star).
Several comets are observed for astrometry, photometry and Af(rho): comet 21P, C/2015 O1, C/2017 M4, C/2017 S3 and C/2018 C2 Also spectroscopic high resolution (H-alpha detail) of some Be-Stars: gamma Casseopeia, kappa Draconis and omicron Andromedae.
During the night of 4/5 june, i did observations of comets: 21P, 30P (not found), 187P, C/2010 U3, C/2015 O1, C/2017 E3, C/2018 C2 Also 2 spectroscopic observations in high resolution (1800 l/mm grating with … Read more
After the calibration of the mount, i did some quick observations of comets during the evening/night. Weatherconditions are bad ancd high clouds are coming in and also high humidity. Comets that are observed are: 21P, C/2015 … Read more
