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.

NGC3580.

NGC3580. I took this image using Astronomik narrowband filters SII, OIII and H-alpha and I used the Hubble Palette for the colour data. The setup I was using was 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 combined them with flat field frames to reduce the effect of vignetting in the final image. The total exposure times were 40 minutes for each filter.

B33 The Horsehead nebula

Filter Test. Here we have B33 the Horsehead nebula, imaged 30 degrees away from the full moon under clear sky conditions. The total exposure time was 2 hours and twenty minutes. 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 filter was an Astronomik H-alpha filter.


This is a combination of old and new data. The total exposure time was 5 hours.

NGC2264 The Cone nebula.

NGC2264 The Cone nebula. This is the southern region of the same cloud that contains the Fox Fur nebula, lying at a distance of about 2,700 light years in the consellation of Monoceros. I was using my ten 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, SII, OIII and H-alpha. 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 for each filter was sixty minutes.
