This image was taken using the HST palette and was made up of 6x10 minutes unguided for Ha OIII and SII. It was taken with a TMB 115 f7 and Starlight Xpress H36 camera on a Paramount ME. This is quite a wide field and includes other deep sky objects including the open cluster M 52. No flats or bias frames were used in the callibration, just simple auto dark subtraction
