Complex in Perseus
very faint emission/reflection nebula complex in Perseus rides
high on January evenings, making an excellent target for long
exposure H-Alpha imaging to record its faint outer extensions.
It is indeed also a very different type of object to color balance
as well. Because it is a combination of yellow dust, and red
nebulosity, the main nebula is not completely red. More of an
orange color with the blend. The blue parts of the nebula, which
represent the reflection nebulosity, is suppressed in this image
because of the red filtration. |
