Central in the image is the blue OIII emission line "sprite" structure of SNR G013.3-01.3. This SNR is in a field of Ha emission identified as Sh2-41 (also LBN 51). The distance of this SNR has been somewhat elusive with SNRCat indicating anywhere from 6,500 light years to 13,000 light years. The filamentary Ha emission below the blue sprites of the SNR and those to the left are believed to be part of the SNR shell. These filamentary Ha structures appear to be extensions of the dimmer blue OIII emissions .
This is a busy field aside from the main attraction of the SNR. Dark nebulae are LDN 336, LDN 335 (Barn 307), LDN 321 and 328, LDN 327 (Barn 92), LDN 327 (Barn 93) and a string of dark nebulae (Dobashi Catalog) in the lower right. Bright Nebulae seen are LBN 52 and Sh2-39. Open clusters seen are NGC 6613 (M18), NGC 6603 (Collinder 374, Melotte 197), and Biurakan 5.
