That's not bad at all.. 6" f5 is 30" so the focal length is 760mm. I assume that is guided right?
My 4-minute unguided subs at 600mm show a tiny bit of elongation due to declination drift..

IT must have coma corrector, if the object is not in center. I took he image out of center to have a look. Thanks.
