The galaxy M83 in Hydra.
This image is a stack of 63 sixty second exposures using a Vixen R200SS 8" f/4
Newtonian with a coma corrector.
It was tough to shoot, as it only gets 12 degrees above the horizon from
my observatory, and at its highest point is surrounded by the light dome
from NYC and northern NJ, so there is a fair amount of light pollution and
unsteady air to contend with.
The image was calibrated, defect corrected and stacked,
followed by 5 iterations of Richardson-Lucy deconvolution,
then a simple linear stretch was performed, all using AIP4WIN.
This image has been resampled down from its original size of 1200x960.
