NGC 507 and NGC 708 galaxy groups

NGC 507 Galaxy group . This group of faint galaxies lies in a chain in the constellation of Pisces at a distance of about 213 million light years. This image was taken using a ten inch F 4.8 reflector, PHD auto guiding with an Atik 383L mono CCD camera. Five minute sub frames and dark frames was captured and combined with flat field frames to reduce the effect of vignetting in the final image.The total exposure times was 60 minutes using a red filter , 60 minutes using a green filter and 50 minutes using a blue filter.

NGC708 group . This group of galaxies lies deep in the constellation of Andromeda. I was using a ten inch F4.8 reflector, PHD auto guiding and an Atik 383L mono CCD camera. I captured five minute sub frames and matching dark frames and combined them with flat field frames to reduce the effect of vignetting in the final image.The total exposure times was 60 minutes using a blue filter, 60 minutes using a green filter and 30 minutes using a red filter.
