Tony,
Great comments and advice from Alex
Startools , yes give it a go , I’ve been using it for 4 years now and it’s so easy to use , very powerful and works well with all levels of data
DSS , I use DSS to stack my L Extreme subs , even when I lower the threshold to 2% I only achieve 20 or 30 stars ( 10 stars is enough to stack )
Checking Subs , I use ASTAP to check my subs ( fits files ) works really well, opens and stretches fits files for close examination, recommend it
Cheers
Martin
