Description:
117X-NGC4361-PNe is round with soft diffused edge. The central star is easy. The PNe is difficult without a filter. With the O-111 filter the contrastn is improved, but not a lot of detail revealed.
203X-NGC4361 with the O-111 filter is considerably dimmer. I can detect, just a hint of the x-structure? The better view at 203X is without the O-111 filter, but not a lot of detail is detected. The central star is easy. Light pollution is killing the contrast.
