NGC 604, Imaged with an
AP 10" f/14.6 Maksutov-Cassegrain
The L channel images were taken in unbinned mode. There are 5 images, 10
minute exposures each. They measure between 4 and 6 pixels FWHM. This
corresponds to 1.6 to 2.4 arc sec. The color images were taken at 2x2 and 3x3
binning with 10 minute exposures. There are 2 each of the 2x2 and 3x3 color
images. I did 3x3 binning to get deeper into the spiral arm, but my local sky
pollution interfered greatly.
