The star Merope and its Nebula NGC 1435/IC 349 in in the Pleiades
The most conspicuous of the
Pleiades reflection nebulae is NGC 1435 around
Merope, also called "Tempel's Nebula", as it was discovered by
Wilhelm Tempel on October 19, 1859.
This is the only one of the reflection nebulae in the Pleiades which was known
to John Herschel when he compiled his General Catalog (GC) in 1864, and has
been assigned the number GC 768. In the NGC, it is described as very faint,
very large, diffuse nebula around Merope; its angular diameter is given as half
a degree (same as the Full Moon).

The Merope Nebula contains a bright knot, IC 349,
which is very small and 36" south following (east) of Merope (more exactly, at
position angle 165 deg). This small reflection nebula was first discovered by
E.E. Barnard in 1890. It appears such bright, compared to its suroundings,
because of its proximity to the star Merope.
