Quick look low resolution spectrum. Reveals a bright continuum with strong hydrogen emission lines and some other as yet unidentified emission lines. Field is 12 x 6 arc minutes and conveniently includes an ‘ordinary’ A-type star spectrum for comparison(!) with hydrogen absorption lines. Taken with a 26cm, 3 degree objective prism on a 12inch F/3.6 astrograph. 24 x 20 seconds. 19th March 2021 at ~21:00GMT.
