The Milky Way

After 1:00 am, when the full cutoff LED street lights are turned off, the difference in the sky is remarkable; stars become visible overhead down to about magnitude 5.3.

The following image was captured using a Canon 10D set at ISO 3200 with an 18mm lens at f/2.8. I took twelve ten-second subframes along with matching dark frames to minimize noise in the final image.

Another image was taken from my backyard in Newport at 2:00 am after the street lights were off. The Milky Way was clearly visible with stars down to about magnitude 5.4.

For this, I used my Canon 10D DSLR camera set at ISO 3200 on a tripod, with an 18mm lens at f/2.8. I captured 16 fifteen-second subframes with matching dark frames and stacked them using Deep Sky Stacker software.

M11 and M27

M11, The Wild Duck Cluster: Captured using a 10-inch f/4.8 reflector, Vixen Atlux mount with PHD auto-guiding, and a Canon 50D DSLR camera. I took 30-second subframes, integrating them with corresponding dark and flat field frames to minimize noise and vignetting. The total exposure time amounted to 15 minutes.

M27, The Dumbbell Nebula: This image was obtained with a 10-inch f/4.8 reflector, Vixen Atlux mount, PHD auto-guiding, and a Canon 50D DSLR camera. The camera was set to ISO 3200, capturing 30-second subframes, which were then merged with matching dark and flat field frames to lessen vignetting effects. The cumulative exposure time was 20 minutes.

M27, The Dumbbell Nebula: The image is a composite of data from two cameras, a Canon 50D DSLR and an Atik 383L mono CCD, utilizing narrowband filters: H Alpha, OIII, and SII.

The aurora on the 10th of May 2024

Images of the aurora on the 10th of May 2024 . I have reprocessed them stacking six two and a half second exposures together using Deep Sky Stacker.

M13

This image of M13 was taken using my Canon EOS D50 DSLR camera. I set it up at prime focus using my 10 inch f/4.8 reflector, an IDAS filter mounted on a Vixen Atlux mount. I captured 10, 15. 20 and 30 second sub frames with matching dark frames.  Total exposure time was 15 minutes. The data was then averaged and stacked using deep Sky Stacker and Paint shop Pro software.

Aurora of May 10th

I was using my Canon EOS D50 set at ISO 3200  with an 18mm lens. The exposure times are 2.5 seconds.

Thor's Helmet

Here we have data taken using two telescopes, a 4 inch  f/6.3 refractor combined with data taken using a 10 inch f/4.8 reflector.

The Eyes NGC4435 and NGC4438 .

This group of galaxies lies in the centre of the Markarian chain, the heart of the Virgo cluster. I was using a ten inch F /4.8 reflector, a Vixen Atlux mount, PHD auto guiding , an Atik 383L mono CCD camera and a blue filter for the luminance data. I captured 60 minutes of data using the camera set on X1 bin mode with five minute sub frames and 30 minutes of data with the camera set on X2 bin mode taking 1 minute subframes. This data was then combined together with matching dark frames and flat field frames to reduce the effect of noise and vignetting in the final image. Finally I combined  this with old colour data taken using a 4 inch refractor.

The night sky from Newport wetlands

The camera was set on ISO 3200 a Cannon 50 D . The lens was set at 18mm a F4 capturing  8 sets of 4 second exposures . I averaged them together and averaged again calibrating the position of the stars due to the rotation of the earth .

Thor's Helmet

The following images of NC2359. Thor's' Helmet 'was taken on 9 seperate evenings  with additional data added,  an extra  55 minutes using a blue filter, 1 hour using a H Beta filter and 2.5 hours using an O111 filter.  I also used a high pass with an unsharp mask filter to enhance the central detail. Notice the bright star in the centre, a Wolf-Rayet star.

M42 and Thor's Helmet

This image of M42 contains old and new data. 30 minutes using RGB filters, 6 hours and 10 minutes using a H A filter, 2 hours and 45 minutes using an O111 filter. 2 hours and 10 minutes using a S11 filter and an additional 60 minutes using a H Beta filter . The data were captured using a 4 inch F/6.3 refractor , a Vixen Atlux mount and an Atik 383L mono CCD camera .

NGC2359 . Thor 's Helmet  nebula. This emission nebula lies in the constellation of Canis Major at about 11.000 light years away from us and is about 25 - 30 light years across . I took this image on 4 separate evenings using my 10 inch f/4.8 reflector, a Vixen Atlux mount, PHD auto guiding, a set of Astronomik RGB and narrowband filters , HA. O111 , S11. I captured 5 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. The total exposure time was 3 hours 30 minutes using a H A filter, 90 minutes using a S11 filter, 1 hour using an O111 filter and ten minutes using a blue filter. A total exposure time of 6 hours and 10 minutes.
