FeatureRequest: Ignore specific regions when plate solving #59

Open cpoole opened 1 year ago

Hey AstroImageJ team,

some of the newer CMOS cameras from ASI and QHY use the first N rows of an image to encode metadata about the image. When performing a plate solve these pixels are picked up and confuse the plate solve.

It would be great to have a feature in the Astrometry Settings menu to restrict the dimensions of the image used for plate solving.

I'd be happy to submit a PR for this work, I'll just need a bit of guidance around the testing process

Would it be possible to share one of these images with us? I am curious if they have anything in the header to indicate the number of reserved rows, or if they have a separate HDU in the file with just the image.

I'm curious why they have done this when there are better ways to have stored the metadata.
