Thanks Ganesh, you are right a min long exposure is still too long but any exposure less than a minute long was not capturing the subtle brown shade of the milkyway, and the fastest lens I had was a f2.8 but of 90mm which was giving a narrower field of view. So I guess I had all the straws drawn.
I applied 30% of neat image noise reduction as it was taking away the texture of the milky way if I over did the neat image. As they say sometimes the best things are kept just for the eye to see and enjoy.
