Description:
An unexpectedly bright, but tiny (20") planetary nebula. If we already know what and where must we look for, it is an easy target. However, for me it was a really tough one for the first time: it took some time to realize that the mysterious "star" that shouldn't be there according to the star maps is in fact the planetary itself. At 71x it is completely star-like, however at 250x we are able to catch its smaller details too. It has an almond shape, elongated to the E-W directions, with a bright white core. Also towards these directions I could discover two faint little horns. It requires high magnification, and good seeing.
