We report an optical spectroscopic observational program of emission-line objects at Bosscha Observatory. The observations were conducted on 18 nights between May to July 2019. We employ the spectrograph NEO-R1000 ( R ∼1000) equipped with SBIG ST-8 XME CCD camera attached to a 28 cm ( F /10) telescope and the spectrograph LHIRES III ( R ∼5000) equipped with SBIG ST-402 CCD camera attached to a 25 cm ( F /10) telescope. Data reduction has been carried out using longslit transform routines within the Image Reduction and Analysis Facility (IRAF). We have successfully obtained the spectra of 9 Wolf-Rayet (WR) stars, 13 B-emission (Be) stars, 2 Luminous Blue Variable (LBV) stars, 8 Herbig Ae/Be (HAeBe) stars, and 1 recurrent nova. The obtained spectra are presented and discussed in this paper.
