Yes … that all looks correct.
I double checked my camera settings (Canon EOS 70D DSLR). The scale and pixel size are correct …
I have bumped up the duration of the plate solve image to 20s at 1600 ISO. I also bumped up the auto stretch to “Medium”.
To test, I used APT with the same camera settings and grabbed an image that ASTAP was able to solve in 20s.
