|Notes:||I'm posting this for now ... but I'm not sure about the background
of this field. The first 65 subs were imaged with an almost full Moon up, and
my neighbor's lamp shinning into the tube during the early part of the
sequence. IC 289 is about 1.5 to 2 degrees north of a couple of Bright
Nebulae (SH2-202 & LBN 667), and about 1.2 degrees NNE of
IC 1871 (a dusty region of the sky). The last
36 subs were taken in a dark sky, and were used as the primary reference
for the the 90 subs I ended up using in CCDStack.
