IC 1396, The Elephant Trunk nebula.

This patch of nebulosity lies in the western part of the constellation of Cepheus at a distance of about 2,500 light years.

I took this image under clear sky conditions with no moonlight, stars were visible down to about magnitude 4.6 . 

I was using my ten inch f/4.8 reflector, a Vixen Atlux mount, PHD auto guiding, a set of Astronomik narrowband filters 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 noise and vignetting in the final image.

The exposure time was 120 minutes using a H-alpha filter, 40 minutes using an O111 filter, 40 minutes using a S11 filter, 25 minutes using a H Beta filter and 20 minutes using a blue filter .

A total exposure time of four hours and five minutes .

NGC7023. The Iris Nebula.

This patch of nebulosity lies in the western part of the constellation of Cepheus. The conditions on that evening were very clear and cold with no moonlight, stars were visible down to magnitude 5.

I was using 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 filters. The filters were H Alpha for red, O111 for green and a blue 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.

The total exposure time was 90 minutes using a blue filter, 30 minutes using an O111 filter and 120 minutes using a H Alpha filter.

Vdb 141. The Hanging Ghost Nebula

This patch of nebulosity lies about one degree east of the Iris nebula, NGC 7023 in the constellation of Cephus.

The sky conditions were not very good on the first evening with very high cirrus clouds, however on the second evening it was very clear. There was no moonlight only light pollution to contend with. Stars were visible down to about magnitude 4.5.

I was using my ten inch F/4.8 reflector, a Vixen Atlux mount, PHD auto guiding, a set of Astronomik narrowband filters, a blue filter 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 noise and vignetting in the final image.

The total exposure time was three hours using a H Alpha filter, 30 minutes using an O111 filter and 35 minutes using a blue filter.

The Tulip nebula

Sh2 - 101, The Tulip nebula. This patch of nebulosity lies in the constellation of Cygnus the Swan at a distance of about 6,000 light years. There is believed to be a black hole to the west of it. The sky conditions were very poor  with high cirrus reflecting the moon light, stars were only visible down to about magnitude 3.5.

I was using my ten inch F4/8 reflector, a Vixen Atlux mount, PHD auto guiding, a set of Astronomik narrowband filters, S11, O111, HA, a blue filter and my 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 noise and vignetting in the final image . The total exposure time was 90 minutes using a H Alpha filter , 30 minutes using an O111 filter , 25 minutes using a S11 filter and ten minute using a blue filter.

NGC891

NGC891 resides in the constellation of Andromeda.

The observing conditions were suboptimal due to poor sky transparency; stars were only visible down to about magnitude 4.3. However, there was no moonlight to interfere, only the light pollution from the city. For imaging, I utilized an Atik 383L mono CCD camera, a ten-inch f/4.8 reflector, a Vixen Atlux mount, and a set of Astronomik RGB and narrowband filters with PHD autoguiding. I captured five-minute subframes and integrated them with corresponding dark frames and flat field frames to mitigate noise and vignetting effects in the final image.The cumulative exposure time was 120 minutes with an HA filter, 40 minutes with an OIII filter, and 20 minutes with a blue filter.

Images from the Exmoor National Park star party,

On October 25th and 26th, I participated in the Exmoor National Park star party, organized by the Yarn Market Hotel in Dunster, Somerset, and hosted by Terry Evans. I captured images of the Milky Way and Comet C/2023 A3, also known as Comet Tsuchinshan-Atas.

I used my Canon 10D with a Tamron 18mm-270mm zoom lens attached to my Astro Track mount. I took two-minute sub-frames along with matching dark frames, setting the camera to ISO 2300.

The Gower night sky with as tracking mount and DSLR

The images were captured using an Astro Track mount, taking four three-minute subframes along with corresponding dark frames. These were then averaged to minimize noise in the final image. The camera used was a Canon 10D DSLR set to ISO 3200.

The Milky way from Oxwich Bay, Gower

I was using a Cannon 10 D DSLR on a static tripod . The exposure times were 30 seconds with matching dark frames.  I then averaged four images together to reduce the effect of noise in the final images.

Milky way images

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.
