This is the first astro image I have taken and edited. I noticed that the stars on the outer edges are elongated but the ones in the center of the image look okay - this appears to happen even during very short exposures so I am assuming it is a result of the OTA...

Looking for any feedback/comments.

Thanks,

Nice image. You can probably expect a bit of distortion at the corners with a reducer. Looks pretty tame to me at this scale.
