A 9-section mosaic of IC 1805 using narrowband filters and IC 1871

9 individual panels adding two extra panels to complete the mosaic.
IC1805 the Heart Nebula . This lies in the star constellation of Cassiopeia next to the Soul nebula. I took this image on 7 separate evenings with total exposure times of 60 minutes for each filter . The
telescope I was using was my 10 inch f/4.8 reflector, a Vixen Atlux mount, PHD auto guiding, an Atik 383L mono CCD camera and a set of Astronomik narrowband filters H-alpha, OIII and SII. 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.

IC 1871 the Soul Nebula . This lies next to the Heart nebula in the star constellation of Cassiopeia the Queen . I took this image on two separate evenings using narrowband filters H-alpha , OIII and SII with total exposure times of sixty minutes for each filter. 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 . This image was taken using my ten inch reflector, a Vixen Atlux mount, PHD auto guiding and an Atik 383L mono CCD camera.

The outermost region of IC1805

This image of the Heart nebula was taken using my ten inch f/4.8 reflector, a Vixen Atlux mount, 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 werw 20 minutes for each R.G.B. colour filter, 40 minutes using  SII, 40 minutes using an OIII filter and 60 minutes
using a H-alpha filter.

A section of sky in the elephant trunk nebula

Here we have another section of sky in the elephant trunk nebula . On this particular evening I had problems with the tracking on the mount and time was very limited . I only had one hour before the telescope would crash into the pier. However I still consider this image as useful.

I was using my ten inch F4.8 reflector, a Vixen Atlux mount and an Atik 383L mono CCD camera. I only used narrowband filters SII, OIII and H-alpha, capturing 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 time was limited to 40 minutes using an H-alpha filter, ten minutes using an OIII filter and ten minutes using an SII filter.

IC1318, The butterfly nebula.

I took this image under very clear sky conditions with stars visible down to magnitude five. The telescope I was using was my ten inch f/4.8 reflector with a Vixen Atlux mount 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 were 60 minutes using a H-alpha filter, 40 minutes using an Olll filter and 40 minutes using a Sll filter.

M57 and its outer shell

This image was taken on two separate evenings. On the first I captured the RGB colour data with total exposure times of thirty minutes for each  filter . however on the second evening I used a total exposure time of three hours using an Astronomik H Alpha filter . The sky conditions were fairly clear with stars visible down to 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 vignetting in the final image . The telescope I was using was a ten inch f/ 4.8 reflector on a Vixen Atlux mount, PHD auto guiding and an Atik 383L mono CCD camera. Notice the galaxy IC1296 near by M57.

NGC6820 and NGC6823

NGC6820 lies near the star cluster NGC2023 in the constellation of Vulpecula at a distance of about 6,000 light years. I took this image under very clear sky conditions with stars visable down to magnitude five. I was using my ten inch F4.8 reflector, a Vixen Atlux mount, PHD auto guiding and an Atik 383L mono CCD camera. The total exposure times were sixty minutes for each narrowband filter and thirty minutes for each RGB filter. I captured five-minute sub frames and matching dark frames and combined them with flat field frames to reduce the effect of vignetting in the final image.

M16 The Eagle Nebula.

From this particular location M16 is low in the night sky and only just rises above the roof tops looking from my observatory, so imaging time is very limited. I only managed to capture two five minute sub-frames using each narrowband (H-alpha, SII and OIII) filters. I then combined the narrow band data with some old H-alpha and RGB luminance data. Using the Hubble palette
colour data to produce the final image. The telescope I was using my ten inch f/4.8 reflector, an Atik 383L mono CCD camera with PHD auto guiding.

Combining images from different scopes

An experiment I tried using Paint Shop pro software, combining three images taken using two different telescopes; a 10 inch, f/4.8 reflector and a 4 inch f/6.3 refractor. The final image was then sharpened using manual unsharp-masking. I used a Gaussian blur filter set at a power of 50 and subtracted 50% of the blurred image from the existing image. I used the layer set on difference on Paint Shop Pro 7. I then blended the sharp image with the existing image set on 60 per cent, resulting in the final image.

Adding data to the cone and fox-fur nebula images

This image of the cone nebula contains old data with added H-alpha luminance data. The total exposure time of the added data was sixty minutes.

NGC2264, the Fox Fur nebula

Here we have a cropped composition of NGC2264, the Fox Fur nebula with added H-alpha luminance. A total exposue time of four hours.
