This nebula is easily seen at only 31x, as a faint disk using averted visión.
Higher magnifications give an very good view. Using 80x and 100x, the big
fuzzy disk almost disappears when observed directly. It has a rather uniform
brightess, with no visible details. The eyepiece field is very rich in faint
