My first shot of M2

M2 on 9/19/07

This image of M2 is the first I’ve gotten and is also the longest image I’ve taken. At over 480 seconds it was a full 8 minutes of exposure time. I didn’t really mean to take an exposure for that long, but I was helping Dave (who came by this evening) with his telescope and camera and I just left it running while I did that. When I came back I found that it had stacked over 60 8 second images and it looked pretty good to me. My next target was the Ring Nebula, but right after I found it, my tracking motor’s batteries conked out. Ah well… I’ll just have to get a plug-in adapter instead so I can run it off my extension cord I’ve started using for my laptop.

Well, it’s really late so I need to head off to bed. I hope you’ve enjoyed the show.

  1. Very cool. It is always nice to have something work out by “accident”

  2. Well done. What cameras are you using? What Telescope? You know all the stuff so I can get going. I don’t kmow if I should go DSLR, have acess to a Nikon D40 and D40X, or should Canon eos 20D better or a purpose built imager ie. SBIG etc.

  3. Pete – I’m using a Meade DSI Color camera at prime focus on my 4 1/2 in telescope. I have a German equitorial mount with a motor that allows the telescope to “track” objects once the mount is properly aligned. Technically it’s not tracking – it’s just moving the telescope at a rate roughly equivalent to that of the night sky. It allows me to take long exposure photography without getting star trails in the picture. You can find out more at the About Me and My Equipment page.

  4. Thanks for the response. Sorry for taking so long to respond but have been having some medical issues rudely intruding into my life.

    I think at this time I will be using a Nikon D40 DSLR using a computer guided setup. At least that is what I am working on investigating at the moment.

    Take care and keep on clicking away.

  5. Sorry to hear that – hope you’re feeling better. In addition to my Meade DSI, I’ve also used the Nikon D50 DSLR. The Nikon DSLR’s have great resolution and can work really well. My issue is that my scope and mount aren’t good enough to take really long exposures with it. Hope you can share youre results.
