Once I found a video on how to merge a mosaic in PI I was full of hope. It all seemed fairly easy and straightforward. Sadly, I've ended up with something of a mess and I don't know why. I'm hoping that someone recognises the issue or at least knows how I can make a start on fixing it.
On the right is the stack of subs, with histogram transformation and nothing more. The stars are not an issue at this stage. On the left is the same area, but after the whole mosaic process. As there are no issues prior to the mosaic stage, I think this isn't a calibration process.
Can anyone help me with this? Have you seen it before? I need to try to address it as the more processing goes on, the worse it gets.
