  2. A blog by Mike O'Day ----------------- When I show my astrophotography images to my friends and family they invariably want to know what they are looking at. 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 create this blog to share 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. ----------------- ----------------- Higher resolution versions of the images in the scrapbook can be found in following galleries Mike's Images or flickr.com/photos/mike-oday 500px.com/MikeODay photo.net/photos/MikeODay
  3. The Sculptor or Silver Coin Galaxy ( NGC 253 ) in the Sculptor constellation - re-processed from the original subs The Sculptor Galaxay ( NGC 253 ) ( Please click / tap on image to see larger and sharper ) .................... The Silver Coin Galaxy ( NGC 253 ) in the Sculptor constellation ( aka the Silver Dollar or Sculptor Galaxy ). Caroline Herschel in 1783 was the first to recordthis bright ‘nebula’ in an area of the southern sky that Nicolas de Lacaille had called the “Apparatus Sculptoris” or “the sculptor’s studio”. Whilst relatively close to us compared to the billions of far more distant galaxies in the Universe, the great size of the “Sculptor Galaxy” and the huge distances involved are still hard to comprehend. To put this into some perspective, the light that is just now reaching one edge of the great disc left the opposite edge when the Earth was in the grip of last great Ice Age 70,000 years ago and the light we now see has been travelling towards us for over 11 million years.
