Thanks again Sterve,
Ive finally had a good look and you did wonders to my data. Like you said you have more control on how the data is interpreted so you have created another learning curve for me which i dont mind one bit
Looks like moving on and trying PI and APP and learning a new workflow.
Thanks for your input Rowland and Ryan even though Steve did all the hard work.
Rowland, this is my work flow and what data Steve had to work with and I'll upload for you as well and you can have a play.
3 x different nights. Each data set has lights, darks, flats and bias accordingly for each ISO.
I stacked each individual nights data into three separate images and then stacked the three together.
It now makes sense that the sum of all the images can increase the noise dramatically.
I might have a go later tonight with the method that Rowland suggests.
I'll send a PM to you Rowland with the link to my data.
I'll put all my data up for public when i get my head around how Google Drive works and how you can set permissions etc.
Cheers
Andy
