Only 2 arc minutes
further north the galaxy NGC 7336 could at best be only another fleck of light.
In city-bound telescopes at low power M17 is but a 6th-magnitude streak of nebulosity, about 15 arc minutes
long, and oriented roughly east-west.
The brilliant white-blue magnitude 2.6 alpha Columbae, which could be seen as the eye of the starry dove, is situated just 38 arc minutes
to the west of the00000000000000 open cluster NGC 2061.
Finally, when you view NGC 6543 from a dark site, try this: Increase the magnification to about 100x then nudge your telescope 10 arc minutes
east of the nebula to the 13.7-magnitude galaxy NGC 6552.
The star alpha Doradus is situated just 35 arc minutes
south of the galaxy NGC 1617 in the same field of view.
Its dimensions of 10 by 3 arc minutes
are similar to the proportions of the much larger Andromeda Galaxy (see page 58).
NGC 4881 is an unassuming elliptical galaxy about 18 arc minutes
from the heart of the Coma Cluster.
During an asterism search a long string of stars about 5 degrees north-west of alpha Grus was found, and although not yet confirmed as a Streicher object in the Deep Sky Hunters Catalogue, this STREICHER asterism is probably one of the longest star strings seen so far--almost 20 arc minutes
long and stands out quite well against the star field (see sketch).
M32, located 24 arc minutes
south of the big galaxy's nucleus, has dimensions of 8.7 by 6.5 arc minutes
These are listed in a table, which gives the cluster magnitude, diameter in arc minutes
, and the approximate duration in minutes that the Moon's edge takes to cross the cluster.
Barely 24 arc minutes
north-west of theta Pavonis is a very special star in the constellation.
The 20th-magnitude fragments, separated by 9 arc seconds, were some 23 arc minutes
southwest of the 13th-magnitude primary.
