NGC1491. I was looking for something new to image. I saw this
one in my Herald Bobroff atlas listed as a bright nebula. So I
decided to image it. It's rather nice. Good colors. I'm surprised
this object isn't imaged more. 10x360s, ISO800, taken
November 2, 2005. I'd never heard of this object before I
imaged it. A nice surprise.
On November 21 I re-processed this one using tips received
from Raimond (Ralon73 of Cloudy Nights) from The
Netherlands. A Median/Blur filter mask applied to the original
image. Then reduced the red channel in all areas but the
nebula. Result: Brighter image with less noise.
On January 20 I re-processed again to improve the background
