Here are some mages of M42, the Orion Nebula, I took a few weeks ago.
They are not the best I have seen, but the best I have done so far. Im working to improve my shots.
Taken with Canon D60, Meade AR5, image details are on this page
Orion Nebula
The shot that is of 2 180sec shots shows a lot of movement in the stars, but I wanted to see what I could do with the longer exposures.
The first shot on this page with no image detail was taken a week before the other 2 and not very good.
I still have a lot of work to do in fine tuning my mount and tracking, but its coming along

| Way cool. How do you combine the images in post processing? |

thanks, there are several free programs astronomers use. The one I have is registax, but i have been having problems with it. So I used the "Stitch" function in Ulead Photo Impact XL and set the transparancy to 65 to manually combine the images. Im not sure how to do it in photoshop, but there is a way.

| I did a lot of astrophotography years ago. For long term exposures I had a camera attachment with a small mirror that offset a little light to an eyepiece. There was a crosshair in the eyepiece that you could place a star near the field into. I had a resistor where I could speed up or slow down the clock drive by just a little to keep the star in the cross hair. Declination was adjusted manually as needed. Of course, you had to have pretty good polar alignment. I was able to do it for a good 45 minutes or so at a time. I used chilled film at the time to lessen reciprocity failure of the film. I don't imagine that long an exposure on digital would be possible. The noise would likely be horrendous. I may dig out my old equipment and try a few 2-3 min exposures and use the software you mentioned. Anyway, thats how I used to do it. |

All three are excellent. Wish I had a nice Meade to try some shot like yours. I have a friens who has a Questar, maybe I'll talk him into a star party. Thanks for sharing
