M85, NGC4394 and M106

M85 and NGC4394 . These to galaxies are located in the constellaton of Coma Berenices . M85 is an elliptical galaxy and NGC4394 is a barred spiral galaxy they both lies at a distance of about 60 million light years .This image was taken under poor sky conditions using a ten inch F4.8 reflector , PHD auto guiding and an Atik 383L mono CCD camera .I captured five minute sub frames with 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 40 minutes in the red, 30 minutes in the green and 25 minutes in the blue.

M106. This spiral galaxy lies in the constellation of Canes Vernatici however it is some times named NGC 4258. It lies at a distance of about 23 million light years shining at about magnitude 9. 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 with 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 50 minutes using a blue filter, 35 minutes using a green filter and 30 minutes using a red filter.

Hubble's variable nebula and M100

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.
