LBN667 in Cassiopeia.
This image is a color composite composed of a stack of 16 eight-minute exposures taken through an Hα filter,
(shown in the image below), used as the luminance channel, and stacks of 8 eight-minute exposures taken through
red, green and blue filters for the colors.
The images were acquired using an STL11000M CCD camera on a Tele Vue NP101is.
The exposures were calibrated, defect-corrected and stacked using AIP4WIN.
This image has been resampled down from its original size of 4008x2672.
