defo infinity focus ;-) steady hand then try and crop after to get you closer ;-) also try to keep iso low and shutter speed longer for better quality so cropping gets you closer without showing up flaws ie noise etc , also find somewhere that doesn't have many street lights to pollute your image with show shutter speeds it will pick up all light so keep your surrounds dark ;-)
please post results ;-)
might be worth checking out some pro tips and then try to take what you can to the 1020 bearing in mind they probs have high zoom , lenses etc
