Andromeda Galaxy on Sept. 4 by David Elmore

Above image recorded at the University of Colorado Alpine Observatory Sunday night.
I used my 8” F/4 Schmidt Newtonian, a multi purpose coma corrector and Canon 6D.  Andromeda is a stack of 14 four-minute exposures.  ISO was only 320 in an attempt to extend the dynamic range.  It appears to have worked since both the edge and core came out.
