Last night I had a look at this nebula with my 12" telescope. My notes read:

At 48x this nebula isn't visible. With UHC a faint smudge becomes visible. With OIII too but less prominent than with UHC. At 88x without filter I see a star to the west of where the nebula should be. With UHC the nebula becomes visible as a small line wich again is less visible with OIII. At 188x the same applies as at 88x but the nebula is much harder to see. I'll need to visit this nebula with a larger aperture.
