The Ghost of Cassiopeiae and Gus Grissom's "Navi"

Gamma Cassiopeiae, the bright star at the middle of Cassiopeia's W, makes this beautiful but dim Ghost of Cassiopeiae Nebula (IC 63 & IC 59) combination emission and reflection nebulae a tough target. I used a combination of short broadband, stacked with long broadband and long dual narrowband exposures to handle the wide dynamic range.
Gamma is also called "Navi" in honor of Gus Grissom and the Apollo 1 crew. This is his middle name spelled backwards. He used backwards versions of the crews names to identify stars to be used for celestial navigation on his star chars. NASA now uses this nickname for Gamma Cas. to honor the Apollo 1 crew.

The 9 hours of broadband color images were taken under Bortle 3 skies at Bad Wolf Ranch, near Lampasas, Texas. 16 hours of dual narrowband OSC images were taken on the two following nights from my home in in Bortle 7 Austin.

25 hours total exposure over 3 nights, combined broadband and narrowband data with short exposures to tame the bright star Gamma Cassiopeiae. 191 1' UV/IR exposures stacked for the star field combined with 70 5' UV/IR UV/IR and 193 5' dual narrowband exposures for the nebulosity.
