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 equiped with C11 + L200 spectrograph with 1800 l/mm grating (Res.power > 10.000). Be-stars which are observed are: HD192044, QR Vul and HD195554.
spectroscopic observations of Be-stars on 13 june 2018
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
spectroscopic observations of Be-stars on 6 june 2018
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).
observations of comets and spectroscopic observations of Be-stars on 5 june 2018
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.

first light of LHiResIII spectrograph
I replaced the L200 spectrograph with the LHiResIII spectrograph with 2400 l/mm grating for higher resolution. As first spectrum i choose X Cygni (HD 197572).
observation of some comet on 3 june 2018
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 O1 and C/2018 C2.
new comet C/2018 K1 (WEILAND) my confirmation on 26 may
Henry Weiland discovered a possible comet on CCD images taken with the ATLAS search system on 25 may. After he posted this on the PCPP of the minor planetcenter, i decided to use a remote telescope to see this object as my confirmation for this possible comet. I could see this moving object on my CCD-images and reported this to the minor planetcenter as well. On 31 may 2018 was this object assigned as comet C/2018 K1 (WEILAND). You can find my image of 26 may on comet C/2018 K1 (WEILAND) on 26 may
primary mirror AG16 back from Orion Optics
I received the 0.4-m primary mirror back from Orion Optics without any charge. This is very professional of Orion Optics to help me with this problem. I tested the mirror with Foucault an ronchi and now the mirror looks very good an correspondiong with the report of OO. I put the mirror again in the telescope, do collimation with Cats-eye tools and placed the telescope on the ASA DDM85 mount. After en evening of polaralignment en calibration, i could start with first light ! The images looks very promising, stars are much better, only i see some pinned optics and the distance of CCD to the corrector isn’ very accurate – i see on the edges some coma. In the center OK.
observation comet C/2016 M1 (PANSTARRS) with remote telescope on 25 may 2018
With remote telescope from iTelescope.net i observed comet C/2016 M1 (PANSTARRS) with luminance and R-Bessel filter for Af(rho) parameter.
