More clusters

Another clear spell allowed me to continue with my moonlit cluster hunting. I managed to target three more in Cassiopeia before cloud brought things to a halt again. Top to bottom they are NGC 7789, NGC 457 & NGC 663....NGC 7789 being particularly dense with many red stars. Details are the same for all three clusters: 10" F4.3 Newt. 10x 240 second exposures @ iso800 with CLS in DSS, CS2 & XAT.
