I photographed Antares area by my D800 and 135mm lens with a fixed FOV. However, the integrated image looks quite distorted as shown.

I am sure I didn't check the item of "dynamic distortion correction" for integrating all the frames. May anyone advise why my integrated image looks so?

Hi Volley Wang @volleywang,

Welcome to the Astro Pixel Processor Forum 😉

As far as I can see, nothing is wrong here.

The weird Field Of View of your data is the result of field rotation between your individual images. The actual visible area of the sky looks good and Optical Distortion Correction did it's task, judgind from the corners. If distortion correction failed, the stars would be misaligned in the corners 😉

In 6) integrate, there is a setting that controls the field of view: Composition Mode

By default it is set to Full, which means that all pixels of all images will end up in the field of view of your integration/stack,

If you would set it to Reference and create the stack, then the integration will be simply have the shape and size of your reference frame.

Please let me know if this is clear and if you have any other questions,

Kind regards,
