Its not like you can rely on good tracking and a long guide exposure !

Well I guess good tracking depends on how accurate I get my PA and PEC. Both need some work to get it more accurate, that will have to happen during moon lit nights, but clear nights are in short supply at present. Protrack would help too.
Imaging at long focal lengths though will require some guide corrects.
