Hi, 

I have a question about stacking images in deepsky stacker.

I have been using a Canon 450D XSi for about three years and just purchased an Full Spectrum modified 

Canon 600D T3i a few days ago.  The pixel size is 5.2 on the XSi and 4.3 on the T3i, resolution in pixels is 

5184 x 3456 on the T3i vs 4272 x 2848 on the XSi.

Will I be able to stack my old data taken the XSi with data taken with my T3i ? I haven't tried it yet... 

I have a lot of good images stored,  I cant believe how much more of the red Ha signal I'm getting with the Modded camera !!

Thanks for any help on this.

 

Derrell.

Sure can, depending on your stacking software. I do it all the time in Astro Pixel Processor. Depending on which frame is selected for the reference for alignment, the other camera will either be scaled up or down to match.
