|Right ascension||11h 14.8m|
|Apparent magnitude (V)||+9.9|
|Apparent dimensions (V)||3.4 × 3.3 arcmin|
|Notable features||Owl-like "eyes" visible through larger telescopes|
|Other designations||M97, NGC 3587|
M97 is regarded as one of the more complex of the planetaries. The 16th magnitude central star has about 0.7 solar mass and the nebula itself about 0.15 solar mass. The nebula formed roughly 6,000 years ago.
The nebula gets its name from the appearance of owl-like "eyes" when viewed through a large (>200 mm) telescope under dark sky conditions with the aid of a so-called "nebula filter." The eyes are also (albeit, not so easily) visible in photographs of the nebula.
