Sharpless 2-216 (Sh2-216) is a large, ancient planetary nebula located in the constellation Perseus. At an estimated distance of roughly 420 light-years, it is among the nearest known planetary nebulae to Earth. Its advanced age—estimated at over half a million years—means the nebula has expanded to...
Why this score
Exceptionally large and ancient planetary nebula with scientific distinction, but extreme faintness makes observation and imaging difficult.

Sharpless 2-68, also written Sh 2-68, is an evolved planetary nebula in the constellation Serpens. Its central star's proper motion through the interstellar medium has affected the nebula's expansion and produced an extended tail, giving the object an asymmetric appearance. The object is studied as...
Why this score
Ancient planetary nebula with delicate elongated form and scientific interest, but very low surface brightness limits visual impact.

Kohoutek 1-16, also designated K 1-16, is a planetary nebula in the constellation Draco. Its central star, DS Draconis, is a very hot stellar remnant with a temperature above 80,000 kelvin and exhibits low-amplitude pulsations. These variations make the object useful for studying the late stages of...
Why this score
Exceptionally hot pulsating central star provides notable research value, while the faint shell offers limited visual impact or recognition.

Abell 24 is a large, faint planetary nebula in Canis Minor, cataloged by American astronomer George Abell in his 1966 planetary-nebula survey.
Why this score
Large delicate shell rewards advanced imagers, but extreme faintness and limited structural contrast keep its reputation narrowly specialist.
