Title: Help with HDR Composition - Incompatible image geometry
Post by: m_abukhalid on 2018 May 24 10:30:25

Hi,

Ive been struggling with this for a while now and cant find a solution. I have a widefield framed image with the orion nebula in one corner and the horsehead/flame nebulae in another that Im using as a reference frame. I also have several stacks of the orion nebula (centered) that Ive stacked together to very good result. I would like to use HDR composition process to bring out the added detail in the orion nebula into the widefield frame.

- All the orion images were stacked and then the resulting image was cropped to just keep the orion nebula
- the integrated image was registered against the widefield image I want to use as the reference
- I then tried to use HDR composition with the two images and got the error Incompatible image geometry. I checked the individual files and the registration was done successfully.

Any input would be much appreciated!

so, for anyone that might see this, its not enough to just register the images to get HDR composition to work. Once I cropped them all using the same crop process it worked. Which was strange seeing as all registered images were the exact same size...
