Ok, having to manage my expectations here. Severely light polluted skies in Brunswick, dark 4.5nm Ha Filter and F/7 system will always be tough on SGP or any software! So manual focusing does the trick. A 4 x 30 min stack without darks and just some noise reduction and stretching applied. Now just need another 40 of these!!
