M97 and M108

This image was taken using an 80mm f/6.3 refractor on a Vixen Atlux mount.
PHD autoguiding was used with an Atik 383L mono CCD camera and a set of Astronomik filters.

10 min sub-frames were captured with matching dark-frames. Flat-fields were used to reduce the effect of vignetting in the final image.

The total exposure times were 20 min using a SII filter, 20 min using an OIII filter and 90 min using a H-alpha filter.

Markarian's Chain

This image was taken under a moonles sky with only light-pollution to contend with.

An 80mm, f/6.3 refractor was used on a Vixen Atlux mount, with PHD autoguiding, an Atik 383L mono CCD camera and a set of Astronomik filters.

Ten-minute sub-frames were captured with matching dark-frames and flat-fields were used to reduce the effect of vignetting in the final image.

The total exposure times were 30min using an OIII filter, 30min using an SII filter and 90min using a H-alpha filter, plus 3 hours using a blue filter.

The Leo Triplet

This image was taken using narrowband filters, H-alpha, SII and OIII. The telescope I was using was an 80mm, f/6.3 refractor.

The scope was mounted on a Vixen Atlux mount. PHD autoguiding was used and the images were captured with an Atik 383L mono CCD camera and a set of Astronomik narrowband filters.

10 min sub-frames were captured with matching dark-frames and they were combined with flat-field frames to reduce the effect of vignetting in the final image.

The total exposure times were 60 min for each filter.

NGC 1499, The California Nebula

This image was taken using an 80mm, f/6.3 refractor mounted on a Vixen Atlux mount.
PHD autoguiding was used with an Atik 383L mono CCD camera and a set of Astronomik narrowband filters.

The total exposure times were 60 min using an OIII filter, 60 min using a SII filter and 3 hours using a H-alpha filter.

ten minute sub-frames with matching dark frames were captured and they were combined with flat-fields to reduce the effects of vignetting in the final image.

NGC 2264 The Christmas Tree Cluster

The image was taken under moonless sky conditions with only light pollution to contend with.

I was using an 80mm refractor at f/6.3, a Vixen Atlux mount, PHD autoguiding and an Atil 383L CCD camera with a set of Astronomik narrowband filters.

The total exposure times were 40 min using an OIII filter, 40 min using an SII filter and 4 hours using a H-alpha filter.

Ten min sub-frames were captured with matching dark-frames and combined with Flat-fields to reduce the effect of vignetting in the final image.

NGC 2174 The Monkey Head Nebula

The image is a composite of three images taken through three different telescopes; a 250mm reflector, a 102mm refractor and an 80mm refractor.

The total exposure times were 100 min using an OIII filter, 140 min using a SII filter and 180 min using a H-alpha filter. This gives a total exposure time of 7 hours.

IC 443 The Jellyfish Nebula

This image was taken using an 80mm refractor on a Vixen Atlux mount. PHD guiding was used with an Atik 383L CCD camera and a set of Astronomik narrowband filters.

The total exposure times were one hour for each narrowband filter, SII, OIII, and H-alpha.

I capture 10 min sub-frames with matching dark-frames and used flat-fields to reduce the effects of vignetting in the final image.

M78 and Barnard's Loop

This image was taken under a dark, moonless night, with only light-pollution to contend with.

Stars were visible down to mag 5. The first two evenings, I used total exposure times of 30 min using an SII filter, 30 min using an OIII filter and 4 hours using a H-alpha filter. On the third evening, I used a total exposure time of two hours using a blue filter to reveal the structure of M78.

I was using an 80mm, f/7 refractor on a Vixen Atlux mount, PHD autoguiding with an Atik 383L monochrome CCD camera.

I captured matching dark frames and flat-fields to reduce the effect of vignetting in the final image.
