Another patch of nebulosity
, although fainter, is situated 1.
41 showed a central nebulosity
of diameter about 3" and a tail about 10" long toward the WSW.
The faint crescent-shaped haze filters out in a soft filamentary nebulosity
towards the north-west.
Only a few arc minutes north of the boundary with Canis Major, approximately 3 000 light-years away, hangs the star cluster NGC 2353 in the southern part of an area of soft nebulosity
In 1895, Roberts questioned the reality of nebulosity
that Barnard had photographed around the star 15 Monocerotis, which Roberts could not discern on his own three-hour exposure of the same region.
The core of this cluster is bright and very light, and an obvious star in the embedded nebulosity
draws the eye slightly away.
2 but is difficult to see due to the surrounding nebulosity
Different types of objects reside in this cloud of nebulosity
and are definitely worth a mention.
For a real challenge seek out Sharpless 2-91, a wisp of nebulosity
not far from Albireo.
NGC 6188 displays a range of nebulosity
with shades from really dark to a light, flimsy haze.
In addition to the bright central star and the outer halo, two small spots of nebulosity
can be seen on either side of the central star.
The middle brighter area is large, with a soft outer halo that displays a good amount of nebulosity
on the fringes.
Bi-polar emission from the star illuminates the dusty gas cloud around the star creating the variable reflection nebulosity
variously known as RNO125, GM29 or Gyulbudaghian's Nebula (Figure 10).
Its fine filaments form streams and loops of nebulosity
indicated as Gum 12, 15 and 17.
Remember that nebula filters only work on emission objects, such as the Veil and North American Nebula; they will not help you see the reflection nebulosity
surrounding the Pleiades, for example.
