arp 166 is the last member of the class diffuse filaments, but see
discussion for arp 162.
arp 166 is located a little east of center. the atlas note is "small spiral at
end of plume". the small galaxy is easy to see in this image but the scale
makes it hard to classify as a spiral.
the north galaxy of the arp 166 pair is ngc 750,
while the southern member is ngc 751. the galaxy about 3 minutes down from
>
about 2 minutes from the right edge is ngc 739. there are quite a number
of small galaxies in the field, including the faint irregular halfway between
arp 166 and the bright star. none of them are in any of the common
catalogs but a number do show up in less-used catalogs.
