The Moon

The Iris nebula

NGC3280 The Wizard Nebula.

This patch of nebulosity lies in the constellation of Cepheus the King commonly  named the Wizard nebula. 

The data were taken on two separate evenings with hazy sky conditions, on the first stars were visible down to magnitude 4.7 and on the second magnitude 4.

I was using my ten inch reflector f/4.8, a Vixen Atlux mount, PHD auto guiding, an Atik 383L mono CCD camera, a set of Astronomik narrowband and RGB filters. I captured five minute subframes with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image. The total exposure time was two hours and forty minutes using a H-Alpha filter, thirty minutes using an O111 filter, twenty five minutes using an S11 filter, and twenty minutes for each RGB filter, total exposure time of 285 minutes, four and three quarter hours.

M27, The dumbbell nebula

This patch of nebulosity lies in the constellation of Vulpecula the Fox.

This image was taken on two separate evenings with hazy sky conditions , stars were only visible down to about magnitude 4.5.

I captured five minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image.

I was using a ten inch f/4.8 reflector, a Vixen Atlux mount, PHD auto guiding, an Atik 383L mono CCD camera, a set of Astronomik RGB and narrowband filters H Apha, O111, S11.

The total exposure time was 150 minutes using a H-alpha filter combined with some old H-alpha data making an exposure time of 250 minutes, the O111 exposure time was 60 minutes, 40 minutes for S11 and 20 minutes for each RGB filter.
