A bright open cluster of 80 stars spanning 16 arc minutes.
Total magnitude 5.9, naked eye under ideal conditions. Look for several arcs of stars,
and a single red star 7 arc minutes south of the cluster's centre.
NGC 2232
06hr 28m
-04° 51'
A large, bright open cluster, mag 4.2. 29 arc min in diameter,
20 stars mag 5 to 11.
NGC 2244
06hr 32m
+04° 03'
Another bright open cluster at magnitude 4.8, 100
stars covering an area some 24 arc minutes in diameter. The brightest six are
arranged in pairs, forming a rectangle - the core of the "Rosette Nebula".
NGC 2261!
06hr 39.2m
+08° 44'
"Hubble's Variable Nebula" - discovered by W.
Herschel in 1783. A bright but small reflection nebula, 2 x 1 arc minutes. Averaging
about mag. 10, this nebula varies in size, shape and brightness, first noticed by Edwin
Hubble in 1916. (110NGC)
NGC 2264
06hr 41m
+09° 53'
A bright open cluster, glowing at mag. 3.9. forming
the shape of a Christmas tree, pointing almost due south. 20 stars mag. 6 to 10.
NGC 2301
06hr 52m
+00° 28'
A bright open cluster, mag. 6.0, 12 arc minutes in
diameter. Very rich, with 60 stars magnitude 8 and fainter.
NGC 2506
08hr 00m
-10° 47'
A fabulous open cluster. 150 stars of mag. 10.8
and fainter in an area only 7' across. Near Canis Major border.
The "Rosette Nebula" - a
large but faint emission nebula, over 1° in diameter. Use low power and a
nebula filter. At high power, dark "globules" may be visible. (110NGC)
IC 2177
07hr 05m
-10° 42'
The "Seagull" or "Eagle" Nebula - a difficult emission/
reflection nebula with several imbedded open clusters (NGC 2335, NGC 2343). Covers 120 x 40
arc minutes. OIII or UHC required, as are superb skies. Located between M50 and Sirius.
A very large emission/reflection nebula, brightest near the "base" of
the "Christmas Tree Cluster" (NGC 2264) Approx. 2.3° in diameter. Try for the Cone nebula at the top
of the tree.
