Started noticing these weird horizontal streaks in subs that would only appear with narrow band and not lum. It seems to have gone away when I turned on the camera's dew heater. Since these are subs it's not walking noise or hot pixels. Doesn't look like dew either since the pattern is too regular. Has anyone seen the same?
This is a 30 second unguided image in H-alpha. The streaks are the horizontal lines.
I have exact same issue. In fact my images have more streaks than the above user. It only happens with 3nm narrowband filters or I would say it is worst with narrowband filters and not noticeable with RGB. I have already changed all USB cable. I am only using the newer USB3 cables coming from ZWO with new camera.
I have tried turning camera sensor cooling on/off. I have separate DC power supply to camera only with AC to DC adapter from ZWO which is rated for 5A. ASIAIR and other gear is powered with separate power supply. I would appreciate any answer on this topic.
