Constellation of Perseus Image

Perseus constellation

In a recently rare clear night, Ivan Walton (CADSAS Astrophotography Director) captured this image of the constellation of Perseus, nearly overhead on the evening of 1st January 2013.

20 RAW frames, each of 10secs. were taken at 800ASA using a Nikon D40 dSLR with a fixed 50mm f1.8 lens.

The frames were then stacked in Deep Sky Stacker software & adjusted in Adobe Photoshop to produce this splendid view of one of the beautiful winter constellations.

Two objects have been identified.

  • Algol (Beta Persei) is the best known eclipsing binary star, ranging from magnitude 2.12 to 3.40 over a period of 2.8673 days!
  • M34 (NGC 1039) is a fine open cluster, which can just be glimpsed with the naked eye.

Ivan Walton (CADSAS Astrophotography Director) captured this image on the evening of 5th December of the well known constellation of Orion.

22 RAW frames, each of 10secs. were taken at 800ASA using a Nikon D40 dSLR with a fixed 50mm f1.8 lens.

The frames were then stacked in Deep Sky Stacker software to produce this splendid view of one of the beautiful winter constellations.

Image taken on 4th December by Ivan Walton (CADSAS Astrophotography Director).

23 x 10secs. frames taken at 800ASA using a Nikon D40 dSLR with fixed 50mm f1.8 lens, stacked in Deep Sky Stacker.

It shows the constellation of Auriga, with Capella (alpha Auriga) the bright zero-magnitude star to the top left of the image.

 

Miky Way Image

Milky Way with Albireo and Dumbell Nebula highlighted

The Milky Way shot by Graham Caller on a very clear night in Sept.

Albireo is the bright star by the red arrow. The Dumbbell Nebula is to the left of the yellow arrow.

This is a combination of 90 x 10 secs exposures, 30 lights and a variety of darks, flat, and bias frames, stacked and processed using Deep Sky Stacker software.

 

Jupiter images, including a composite with moons

On Monday (5th November – with fireworks exploding nearby) we captured some images of Jupiter with the Alan Young telescope.

We used raw format on the Canon dSLR (.CR2), for the images.

Here is an image of Jupiter:

North American Nebula, Deneb and Sadr

GCaller Swan Deneb Sadr North American Nebula

Image captured by Graham Caller of the area in Cygnus, showing the North American nebula (NGC7000).

The nebula is between the brightest star in the shot (Deneb) and the brightest ‘orange’ star at the 7 o’clock position from Deneb. It looks like a reddish fuzzy blur shaped like North America.
