the "Bubble Nebula" extends mainly north of the ionizing emission-line star, mag 8.7 BD+60°2522 (O6.5-type supergiant). Dark lanes are suspected to the north with very faint nebulosity just north of this gap. The main piece of nebulosity curves away from the involved star towards the east but appears brightest at the western edge near the bright star. Only the portion of the rim extending from north to east of the 3' diameter "Bubble" was seen (not the south edge). The view improved with both OIII and UHC filters but not dramatically. Located 6.5' NE of mag 7 HD 220057. M52 lies 35' NE.
