A small reflection nebula positioned just north of the Hyades has a number of NGC1554. The nebula has a span of only about 1.5 arc minutes, might be needed fairly large-ranged telescopes to appreciate with our eyes.
This nebula is reflecting the light of an embryo star of "T Tauri" at just east of the nebula with a brightness of 9th magnitude. T Tauri is an evolving variable star, brightness of nebula is also variable. The nebula has an another name of "Hind's variable nebula" from a discoverer of the nebula.
