My scope is out of action at the moment ( stupid me stripped the thread on the bottom of one of the tube rings whilst chasing the last tiny bit of cone error - as usual, "perfection is the enemy of the good" ).. Anyway, this is one I captured late last year but I could not get the colour balance right. With nothing better to do I played around with it today unitl I was reasonalby content with it. ( click on image to go to larger image ) Details: NGC 104 ( also known as 47 Tucanae ) alongside the far more distant NGC 121 in the constellation Tucana by Mike O'Day ( 500px.com/MikeODay ). NGC 104 - 47 Tucanae, is the second largest Globular Cluster in the sky ( after Omega Centauri ). Only visible from lower latitudes, it was not recorded by European observers until Nicholas de Lacaille did so whilst visiting South Africa in 1751. Containing millions stars and appearing about the size of the full moon, 47 Tucanae is in fact approximately 214 light years in diameter and around 15,000 light years from Earth. The smaller cluster, NGC 121, appears as a companion to 47 Tucanae but is in fact of similar size, more than ten times farther away at around 200,000 light years and belongs to one of the Milkyway's dwarf galaxies, the Small Magellanic Cloud .

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
