This is a combination of a data set taken with my NP127a while in Manhattan KS and data sets taken with a RH305 and a RCOS 14.5" both located at DSW. The rotations were fairly close (modulo 90˚) so they were quite compatible. The FSW provided the smallest FOV so it was the basis of the final crop. The FOVs for the data sets were FSQ 1d56m18.4s x 1d27m33.7s, NP127is 2d20m33.9s x 1d52m27.1s and RH305 1d53m20.2s x 1d53m20.2s x2. While the necessary crop preserved IC1805, IC1795 ended up on the cutting room floor.
