wowzers looks like i might go for the raw methos next time , question is can you still load say 20 raw frames straight into deep sky stacker or do you need to pre process each file first , i have also had problems with ds stacker but i think it may be due to my tracking and focus in my images.
it would be good if anybody knows of a site that explains the use of deep sky stacker and its errors for future use.

p.s just to clarify if i take 3 exposures in raw what is the percentage of darks to the amount of frames i need to take?
dont forget my location is very poor for clouds and l.p
not used vthe neodymium filter on imaging yet but i am assuming it would make a big difference
