Big weird vertical dark line and dark bottom of stars/planets

Hi everyone,
Newbie here!
I just started
Me and my friend bought the following gear:

Celestron 130slt mount
Qhy5iii715c camera- 8mpx and 1.45 upixel sensor size
Startravel 120 telescope ( 120 aperture and 600mm focal)

As you can see it the photo when zoomed out/out of focus

Some dark vertical line appears
And the bottom of the planet/star is becomes dark

I tried using air to clean my camera sensor and my focuser

And when i zoom in/focus well i get the vertical and horizontal lights!

Is This normal? Something wrong? Or needs cleaning?

Please help i couldn’t find a proper solution/explication

Thanks all in advanced
