Another in the quartet of objects including M 52, NGC 7510 and "The Bubble". From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 7538 NGC 7538 = LBN 542 = Sh 2-158 23 13 38 +61 30.7 Size 10x5 17.5" (8/10/91): fairly large elongated emission nebula 2.0'x0.75' oriented NW- SE. Surrounds two mag 11.5 stars oriented SW-NE (PA = 35°) with a separation of 30". The nebulosity extends SW of the pair and is brightest just west of the pair. A mag 15 star is at the SW end and a mag 14 star is 30" W of the southern mag 11.5 star. At 100x using an OIII filter the nebulosity is very bright and a fainter glow also extends east of the pair to a size of 3'x2'. 8": faint nebulosity with two mag 12 stars involved. Appears elongated and fairly large. Easy to view with averted. - by Steve Gottlieb |
