NGC 7635 The Bubble Nebula

Lying in the constellation of Cassiopeia the Queen are NGC 7538, a diffuse nebula, NGC 7635, the Bubble nebula and M52 a bright open cluster.

I took this image using an 80mm refractor at f/6.3, a Vixen Atlux mount, PHD autoguiding and an Atik 383L monochrome CCD camera. I was also using  a set of Astronomik narrowband filters, SII, OIII and H-alpha.

Bi-colour image

On the first evening I set the camera on x2 bin mode, capturing 2.5 minute sub-frames. The total exposure time for each filter was 30 minutes. On the second evening, I set the camera to x1 bin mode for the luminance data using a H-alpha filter; capturing 5 minute sub-frames, and matching dar-frames. Flat fields were used to reduce the effects of vignetting in the final image. The total exposure time in H-alpha was 120 minutes.

The Cave Nebula (Sh2-155)

This emission nebula lies deep in the constellation of Cepheus the King. Its structure resembles the shape of a cave in space.

I took this image using my 80mm f/6.3 refractor, a vixen Atlux mount, PHD autu-guiding and an Atik 383L mono CCD camera with a set of Astronomik narrowband filters.

On the first evening I set the camera on x2 bin mode, capturing 2.5 minute sub-frames with total exposure times of 30 minutes for each of the filters, SII, OIII and H-alpha.

On the second evening I set the camera on x1 bin mode, capturing 5 minute sub-frames using a H-alpha filter. The total exposure time using the H-alpha filter was 120 minutes.

Nebulae in the Andromeda galaxy.

This image was taken under a moonless clear sky with just light-pollution to contend with.

I used an 80mm f/6.3 refractor, and Atik 383L mono CCD camera, and a Vixen Atlux mount with PHD autoguiding.

I captured 5 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 time were 60 minutes using a H-aalpha filter, 60 minutes using an OIII filter and 60 minutes using a blue filter.

This image is a composition of data captured using three telescopes, an 80mm refractor, a 4 inch refractor and a 10 inch reflector.

In St Davids, west Wales on September 17th. The sky was very dark and clear.

I captured these images with a Canon D50 DSLR and an AstroTrack mount using an 18mm to 270mm zoom lens.
