Not original sorry but the last time I tried this target in nb I got a yucky green image that IISers were not to keen on - so hope this one is better. I reallt need to use star masking but am struggling with the technique - I use DSS to calibrate and stack then AA4 to do colour synthesis. PSE for final tweaks. I can generate a mask in DSS but it does not seem to align with my image and am not sure how to use it is PS...
