  1. After waiting a week for the weather to improve, I finally got to see Nova Centauri this morning. Cloud was an issue as was the impending dawn. Even so, the nova was easily visible to the naked eye through light cloud. Kit: Pentax K10D, Chinon 50mm f/1.9 @ f/4. 15s exposure with NR on. Levels tweaked in PSE6 and Topaz Denoise to tidy up the noise. The Southern Cross is at the top an lying on its eastern side.
  2. Update: 3rd June Re-processed to remove slight magenta tint caused by the non-uniform removal of light pollution by the DBE process ( it was being fooled by the very bright image centre ).

  4. Nearby spiral galaxy NGC 4945 in the constellation Centaurus. ( click on image to see full size ) ( This is an update of my image of NGC 4945 with an additional 22 x 360sec images at ISO400. ) NGC 4945 in the constellation Centaurus is a large spiral galaxy about the size of the Milkyway and around 13 million light years from Earth. It is shown here nearly edge-on and is accompanied in the image by a number of far more distant galaxies; the brightest of which is the 10th magnitude elliptical galaxy NGC 4976 (centre left of the image) which is around 30 million light years away.

  5. The Pearl Cluster in Centaurus ( NGC 3766 ) - re-processed version ( clouded in for days now so I've been looking back through my old images and seeing if I can improve them ) The Pearl Cluster is an open cluster of mostly young blue stars approximately 5500 light years from Earth that is only visible from the Southern Hemisphere and shimmers like a cluster of pearls.

  6. Galaxy Centaurus A ( NGC 5128 ) in the southern constellation Centaurus ( please click / tap on image to see full size ) ............ Updated again - to try to bring out more faint detail ... ............ Updated images ... ............. Originals ... ( 100% crop ) Centaurus A is relatively near to us in the local group of galaxies and is around 11 Million light years away. The unusual shape of Centaurus A is believed to be due to an ancient collision between a large elliptical galaxy and a much smaller spiral galaxy. With an apparent magnitude of +6.8, Centaurus A is the fifth brightest galaxy in the night sky and in the middle of the 20th century it was identified as being the strongest radio source in the Centaurus constellation.

  7. Nearby spiral galaxy NGC 4945 in the constellation Centaurus by Mike O'Day ( 500px.com/MikeODay ) ( Still a work in progress really; 10 subs is not really enough for this 9th mag galaxy from my medium polluted skies. These were taken in the last minutes of the wee hours before dawn after I had finished taking subs of comet 252P/LINEAR and I have not had a chance to take any more as it has been cloudy ever since. ) NGC 4945 in the constellation Centaurus is a large spiral galaxy about the size of the Milkyway and around 13 million light years from Earth. It is shown here nearly edge-on and is accompanied in the image by a number of far more distant galaxies; the brightest of which is the 10th magnitude elliptical galaxy NGC 4976 (centre left of the image) which is around 30 million light years away.

This led me to wonder if there was a way I could display my images on a single page together with a few notes on the target object as well as few technical details of the capture for those who might be interested. What I came up with a "scrapbook" like page that combines all of these three elements in a single PDF sheet ( or jpeg image) that ultimately I might combine together to form a PDF book that I can share online or send to friends and family. In the meantime, I thought I might post in this thread each page of my work-in-progress towards volume 1 of my Astrophotography Scrapbook. Any and all comments, observations, suggestions and constructive criticisms will be warmly received. Cheers Mike ps. The pages have been sized to fit full screen on an IPAD
  9. Shimmering like a pearl to the naked eye, this open cluster of mostly young blue stars ( known as the "Pearl Cluster" ) is approximately 5500 light years from Earth and was discovered by Abbe Lacaille in 1752 from South Africa. A Cluster of Pearls in the Southern Skies ( NGC 3766 " The Pearl Cluster" ) ( please click / tap on image to see larger and sharper - a full size image can be found here ) This HDR image is constructed from 11 sets of exposures ranging from 1/4 sec ( to capture the centre of the brighter stars ) through to 240 seconds ( for the fainter stars of the Milky Way ). Total exposure time was around 5 hours. ..... Image details can be found here
