Something different – a few astrophotos


Well, we finally got some decent weather last week (not raining, but not so hot and humid that I could not really see much), so I had a shot at some astrophotography. My equipment is:

  • Celestron CPC 1100 Telescope
  • Alt-az mount
  • Canon XSi DSLR camera

Since I do not (yet) have an equatorial wedge for my telescope, I am limited in the exposure lengths I can use to about 10-30 seconds before field rotation ruins the image.

My first attempt was a simple star picture – Albireo – which is a pretty double star in the constellation Cygnus. This is a stack of 10, 15 second exposures:

Albireo

My second attempt was of M13, a globular cluster in the constellation Hercules. This is a stack or 15, 15 second exposures:

M013_2

Finally, I decided to try M57, the Ring Nebula, in the constellation Lyra. This is a stack of 20, 15 second exposures:

M057_3

As I say, these are my first attempts at non-lunar, non-planetary images. I wanted to quickly work with a low number of images to stack initially, to see if I could get reasonable results. Next chance I get, I will focus more on one object, and go for a larger number of images to try to get more detail, better noise, etc. I am also just learning to use the image processing software, which is a major effort in and of itself.

(someday I will get a wedge, and be able to try longer individual exposures).

About

I have been working in the world of technology for 25-odd years. I am an entrepreneur and consultant, focused on software solutions, social networking, and innovation processes. Currently, I am a Principal Consultant with T4G Limited, specializing in Portal Technologies (including SharePoint), software/systems development, service oriented architectures, and many other things which I will probably not remember until I need to use them. Prior to that, I was VP of Technology at Whitehill Technologies, Inc., where I spent almost 9 years helping to grow the company from a start-up to one of the most successful private software companies in Canada. Prior to that I worked on internet conferencing using early VoIP, and on large military communications projects. Before even that, I worked in satellite control, and remote sensing. Going way back to university, my focus was on theoretical physics and astrophysics. Currently my interests revolve around most aspects of software development, from technologies to management, and in the area of defining sustainable, repeatable processes for innovation within technology organizations. I also have a particular interest in Tablet PC technologies – I have been using one for several years, and I love it. On the personal side, I still have a strong interest in all aspects of science, especially physical sciences, as well as philosophy and comparative religion. In addition, I am into music, playing guitar (badly, I am sorry to say), and reading almost anything I can lay my hands on. I am also a member of the IEEE/IEEE Computer Society, and of the Association for Computing Machinery.
