What are these bandings in my test image

#1

Post by Kopa »

Hi all,

While learning and testing platesolving/livestacking /tracking I got these strange bandings in one of my imaging sessions.

I wasn't really after image quality so was imaging through glass window but I have not seen these patterns before in other imaging sessions taken from the same position.

How could I avoid getting these in future?


Kind regards

Hi Vince,

was this using a cooled camera? Could it possibly be dew or frost on the sensor or the sensor window? That's the thing it looks most like to me.

cheers,

Robin
