This is the final result of my nearly two year
quest to take a tricolor narrowband shot of the Heart and Soul (fetus?) nebulae
in Cassiopeia.
This is a total of 6 hours and 50 minutes exposure
over two nights.
Also included is a map of the area, it is indeed
rich in named nebulae and clusters.
there is a small hydrogen-rich nebula toward the
center, just east of IC1805. Does anyone know what its name is?
I've consulted my usual references including the
Millennium Star Atlas with no luck.
The image was taken using a medium format Pentax
Takkumar 200mm f/4 lens used wide open and attached to my Finger Lakes IMG6303E
camera. I took 30 minute exposures for Halpha and [SII} and intended to do for
[OIII] but made a mistake and shot 20 minute Oxygen exposures
instead.
The palette is [SII] = Red, Ha = Green, [OIII] =
Blue, the normal wavelength-ordered palette used in the Hubble Pillars of
Creation.
