In both 8 mm and 5.5 mm oculars, there is a suggestion of a galaxy next to two threshold stars [Vm~16]. In 3.5 mm with movement, a nebulosity is visible that extends orthogonally to the stars to the SW, closer to the NW star. It is much wider than on DSS.

In 5.5 mm with an OIII filter, the nebula is immediately visible on the NW edge of the star glare. It is round, gradually brighter to the middle, edges diffuse. Three faint stars form an arc to the N, leading E to a brighter star.
