white lines from below bright start

jcdc

Hello,

New to the forum. I was imaging the horsehead and after stacking and a mild curve stretch there where solid white lines coming from below the brighter, larger stars.

I took 40 subs at 2min each using asi294MC pro at unity gain. Focal ratio was F7 and filter was the L pro.

Lines where dead vertical, stars were round, guiding was good.

Is this a "blooming" issue. Was the exposure time too high.

Any help would be appreciated

Thanks

Jim

Hi Jim,

Do not worry, CMOS will not generate blooming.

Could you share with us the RAW image files?

I would like to have a further check on the image.

Thank you in advance!
