The discovery history of the
galaxies associated with
the 11.7-magnitude elliptiNGC 2332
cal NGC 2340 in Lynx offers
a window into the type of
IC 458
detective work that goes
NGC 2330 into unraveling designation
IC 461
discrepancies in the New General Catalogue (see sidebar
at right). You'll find NGC 2340
about 13° northeast of Beta (β)
Aurigae and a bit more than
2½° northwest of 21 Lyncis,
where eight galaxies brighter
than 14th magnitude share
its 1° field of view. Its closest
bright neighbors to the southwest form a splash of galaxies
from the Index Catalogue,
including IC 458, IC 461 and

IC 464. Some 15′ to the west
is NGC 2332, a 12.8-magnitude spiral. Placing NGC 2340
at the southeastern edge of
your field of view should capture four of the brighter NGCs
in the area to the northwest.
NGC 2326 is a 13.1-magnitude
spiral about 42′ northwest of
NGC 2340. From there, some
24′ west-southwest brings you
to 11.9-magnitude NGC 2320,
flanked by two barred spirals:
13.8-magnitude NGC 2322 to
the southeast and 13.6-magnitude NGC 2321 almost
directly north. Be sure to scan
around as there are several
other galaxies just outside of
the field.

NGC 2389
A bit more than 2° northwest of
Castor in Gemini is a group of
seven galaxies within range of
an 8-inch scope. The brightest of the bunch is NGC 2389
at magnitude 12.9, and it's
the easternmost of a string of
six spirals that includes NGC
2388, NGC 2385, NGC 2379,
NGC 2375, and NGC 2373,
stretching off to the west in

NGC 2393

that order. The online database
SIMBAD lists NGC 2378 as the
primary designation for NGC
2379, and some other references confuse the two, but according to Corwin, NGC 2378
is clearly just a double star.
The seventh bright galaxy in
the field is the 14th-magnitude
spiral NGC 2393 lying nearly
16′ northeast of NGC 2389.
