Help needed with image integration
« on: 2013 May 02 10:52:58 »
Hello All,
I'm a newbie. This is my first post on this forum. Thanks for all the wonderful tutorials and tips. I have learned a lot through them.

I have a problem with "ImageIntegration" of DSLR images. Can you all please help me out?

I took a few meteor photos with canon 450d dslr on "Geminids" day. I tried to integrate them using Maximum function of ImageIntegration tool.

I got a resultant FITS image. When I open it, it opens three images.
1. Light_Binning_1_rejection_High --> This photo has all the meteors
2. Light_Binning_1_Rejection_Low --> This photo has some foreground (lamp post)
3. Light_Binning_1 --> This one has all the stars and the milky way.

I want to combine 1 and 3 and make a photo with the stars and the meteors in one photo.
I have attached the screenshot with the post.

Can you please help me out with this?

Thanks and Regards,
Keerthi

the rejection maps are "binary" - if a pixel was rejected from any sub during integration, that pixel is a '1' in the rejection map. all the data is lost.

the rejection maps are just there to help you decide if you are rejecting too many pixels/real data during integration.

for this application, just turn off pixel rejection entirely.
