LBN 258, GM 2-41, HH 1037.1038.1039.1040 (Cygnus) * June 2017 * ASA N12 astograph (f/3,6 1081mm) * DDM 85 mount * G3-16200 Moravian EC * Baader LRGB filters * L:420 minutes R: 250 min G:190 min B:270 min * Thanks to Mr. Sakib Rasool for suggesting me to image this area in 2016. GM 2-41 and LBN 258 are a reflection and emission nebulae (bluish -ray GM 2-41 , LBN 258 is red , left and below GM 2-41) close together in a vast dark cloud, which is located in a massive star brewing area (Cygnus X ) in Cygnus constellation, with many Herbig-Haro (HH) objects and Ha emission stars. 43 stellar objects with Ha emission are discovered by slitless spectroscopy in a 14’×14' area near the nebula GM 2-41 located in the HII region DR 15 at the southern edge of the Cyg OB2 association. Emission is detected for the first time for 30 of these objects. Based on VI and JHK photometric data, the overwhelming majority of these objects are classified as young stellar objects in spectral classes F7-M3 with ages of ~1 Myr. The stars are distributed nonuniformly and form two groups which have the same coordinates as the UCHII regions G0.79?+?0.3 and G79.2?+?0.4.
