The Ring and the Dumbbell Nebulae

These images were taken using a Altair ED 2X two inch Barlow lens, a ten inch F 4.8
reflector , PHD autoguiding and an Atik 383L mono CCD camera.  The bright planetary
nebula M57, the Ring nebula, shines at about magnitude 8 and lies in the constellation of
Lyra the Harp . Five minute sub frames were captured with matching dark frames, making
total exposure times of twenty minutes for each colour channel . The same equipment and
exposure time were used for M27 , the Dumbbell nebula.

NGC4435 and NGC4438: The Eyes

These galaxies lies deep within the Virgo cluster at a distance of about 52 million light years . This image was taken using a ten inch f/4.8 reflector with PHD auto guiding .This is a composition of two images taken using two CCD cameras. An Atik 314L was used for the core luminance and the surrounding luminance with an Atik 383L mono camera  . The exposure times was 60 minutes using 60 second sub frames using the Atik 314L camera and 30 minutes for each colour filter with five minute sub frames using the Atik 383L camera .

NGC4567 and NGC4568

NGC4567 and NGC4568 . These to galaxies are situated in the constellation of Virgo and are commonly named the Siamese twins. This pair of galaxies shine at magnitudes 11 and 12 and lies at a distance of about 80 million light years. A ten inch f/4.8 reflector was used with PHD auto guiding and an Atik 383L mono CCD camera. Five minute sub frames and dark frames were captured with total exposure times of 40 minutes for each colour filter ( RGB filters):

Comet Panstarrs with the Andromeda galaxy and the Cone Nebula

This image of Comet Panstars 4 was taken from Angle on the Pembrockshire coast using a Canon 50D with a 70 mm lens. The camera was set on ISO 400 with an exposure time of 3 minutes. An Astrotrac mount was  used, mounted on a Manfrotto tripod:

NGC2264, the Cone nebula .This faint emission nebula lies at a distance of about 2,700 light years in the constellation of Monoceros . Five minute sub frames and matching dark frames were captured making total exposure times of 90 minutes using a hydrogen alpha filter and ten minutes for each colour filter. A ten inch F4.8 reflector was used, PHD auto guiding software and an Atik 383L mono CCD camera:

NGC3628

NGC3628. This galaxy lies at a distance of about 35 million light years in the constellation of Leo. Five minute sub frames were captured with matching dark frames, making total exposure times of 60 minutes using a red filter, 30 minutes using a green filter and 20 minutes using a blue filte. An Atik 383 L mono CCD camera was used with a ten inch f/4.8 reflector, using PHD auto guiding.

The Bubble Nebula

The Bubble nebula. This image is a reprocessed image revealing its surrounding nebuosity. Five minute sub frames and matching dark frames were captured making total exposure times of sixty minutes using a H-alpha filter, sixty minutes using an O111 filter and twenty minutes for each colour filter. Taken using a ten inch F 4.8 reflector, PHD auto-guiding and an Atik 383L mono CCD camera..

The Rosette nebula

NGC2244 . The Rosette Nebula . This image is a composition taken using an Atik 383L CCD
mono camera, a ten inch F4.8 reflector with PHD auto-guiding. The total exposure time was
ten minutes for each colour filter, 90 minutes using a H-alpha filter and 30 minutes
using an O111 filter. Five minute sub frames were captured with matching dark frames.

The Horsehead and the Flame nebulae

B33, The Horsehead nebula . This is a section of a vast star forming region in the constellation of Orion . Five minute sub frames and dark frames were captured using an Atik 383L CCD camera, a ten inch f/4.8 reflector and PHD auto guiding software. The total exposure time was 90 minutes using a H-alpha filter and 15 minutes using RGB filters.

NGC2024. This hydrogen emission nebula lies in the star forming complex of Orion the hunter at a distance of about 1,500 light years. Five minute sub frames were captured and combined with matching dark frames. The total exposure time was ninety minutes using a H-alpha filter and twenty minutes using RGB filters. This image was taken using a ten inch f/4.8 reflector, PHD auto guiding and an Atik 383L mono CCD camera.
