s30 pro weird vertical & horizontal line problem

siuba

Dear Sir,

few days ago i got the 1st lot of s30 pro, few photos where taken in eq mode at the past few days, around 5 deep sky objects i have taken, but 2 of them got a weird lines problem, my first photo was IC434 with eq mode, 59s x60, live stacked, both jpg & fit (also every single fit) got a vertical line

this one is 1st day (60s x59, eqmode, internal IR-CUT filter)

and this one is 3rd day just few hrs ago (60s x60 eqmode, external 7nm filter)

both image i just edit the original jpg stacked file and +1EV in photoshop to let you see it more clearly, i m thinking is it internal filter edge miss align problem?

Regards,
siuba

Siuba, the vertical lines you are seeing are likely caused by light pollution or uneven illumination rather than a misalignment of the internal filter.
I recommend performing a flat-field calibration before your imaging session to correct for uneven lighting and any vignetting. Make sure the light source is even and diffuse.

the first line could also be a satellite trail that has been partially averaged out by stacking
