stacking images for astro use
« on: December 21, 2012, 01:12:12 PM »
I have been messing with a program called registax which takes video files and stacks them to create a high resolution image.  Today I thought to myself what if I try magic lanterns HDR video to enhance the amount of data available to adjust in the final image?  Unfortunately I went outside and it was cloudy so I will have to wait another night.  I was wondering if anyone could think of any other creative ways that magic lantern could help benefit this process?

I don't know about ML's HDR video mode, as I would have thought the data content would be much lower than shooting in RAW. But I may be wrong.

I have used the ML intervalometer to take multiple images of star fields and then used software to stack the images with the intention of reducing the hi ISO noise content, ie I was shooting at an ISO of 1600 or 3200.

I use Intervalometer to take the stacking picutres in RAW format.  It sure frees up my finger for other more important things like scratching...  ;D  Thanks to ML!

Google a program called deep sky stacker.

Also go into your camera options, and turn on Long exposure noise compensation.

This is 36 intervalometer'd pictures stacked together, F1.4 35mm ISO 800, 10 sec exposure using Deep Sky Stacker:

On a really clear night with no moon out, away from the city lights. Still pretty amazing the detail you can see though.
