  1. I just came in from a quick and cold viewing. As I was sweeping the sky east of Pollux and Castor, I came across a large open cluster that I estimated to be a bout 2 degrees across. I just looked up large open clusters near Gemini and found out I viewed the Beehive Cluster or M44. It's also known as Praesepe. In all my years of viewing DSOs with my scopes I never saw this. Possibly because it's so large that only about a quarter of it would have fit into my eyepiece FOV.
  2. Took this on Wednesday with my Dslr, baby Tak on Star Aventurer. 37 1 minute subs at iso 800 with ClS clip filter stacked & processed in Pixinsight. Although I used a bahtinov mask I think my focus might be out a touch as I have small red rings around some stars. I’m finding it very difficult to get good star colour, I’m not sure why so any help will be gratefully received.
  3. Visible for much of the night until around 4.15am, the closest approach is at around 2.15am when the 76% illuminated Moon will be 2 degrees 36" away from M44, the Beehive Cluster. Best seen in binoculars or a wide field scope.
  4. The Southern Beehive Cluster ( NGC 2516 ) in the constellation Carina - by Mike O'Day ( 500px.com/MikeODay ). Because of its similarity to the “The Beehive Cluster” ( catalogued as M44 by Messier ), NGC 2516, which is only visible from lower latitudes, has become known as the “Southern Beehive Cluster”. At a distance of around 1300 light years, NGC 2516 is relatively close to us and resides in the same spiral arm of the Milkyway as we do. Containing around 100 stars, with a number of them in the magnitude 5 to 6 range, NGC 2516 has an apparent magnitude of 3.8 and is visible to the naked eye as a small bright hazy patch at the edge of the Milkyway.

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
