This group of galaxies lies in the centre of the Markarian chain, the heart of the Virgo cluster. I was using a ten inch F /4.8 reflector, a Vixen Atlux mount, PHD auto guiding , an Atik 383L mono CCD camera and a blue filter for the luminance data. I captured 60 minutes of data using the camera set on X1 bin mode with five minute sub frames and 30 minutes of data with the camera set on X2 bin mode taking 1 minute subframes. This data was then combined together with matching dark frames and flat field frames to reduce the effect of noise and vignetting in the final image. Finally I combined this with old colour data taken using a 4 inch refractor.
