NGC 2261 Hubble's variable nebula.This bright nebula lies in the constellation of Monoceros at a distance of about 2,500 light years. This image was taken under poor hazy sky conditions with bright moon light to contend with. I was using a ten inch F 4.8 reflector, PHD auto guiding and an Atik 383L mono CCD camera. I captured five minute sub frames with matching dark frames and combinded them with flat field frames to reduce the effect of vignetting in the final image.The total exposure times was 30 minutes using a red filter, 25 minutes using a green filter and 30 minutes using a blue filter.
M100. This face on spiral galaxy lies in the constellation of Coma Berenices at a distance of about 55 million light years. I was using my ten inch F 4.8 reflector, PHD auto guiding an an Atik 383L mono CCD camera. I captured five minute sub frames with matching dark frames and combind 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, 40 minutes using a green filter and 35 minutes using a red filter.
