My first pictures showed quite a lot of purple fringing, which I could reduce in post processing but I wasn't really happy.
This is a 4 sec exposure (All I had left after deleting longer exposures)
RAW converted to jpg straight out of camera no filter
I had on order from China an SVBony "CLS" filter. It arrived today and as luck would have it the sky was clear.
This is the first output from the scope and filter. I'm very happy now, both Light Pollution and "Purple Fringing" suppressed
This is a 20 sec exposure RAW converted to jpg straight out of camera with CLS Filter.
