Hi Humayun,nice effort dude ! to really deal with the noise mate you need longer exposures . Try at least 30 second subs but If you mount and polar alignment is up to It 60 second subs would come out great ! and align and paste your 15 second sub in for the Trap . It's a long road to creating a great image Humayan and the mistakes we make
and the advice we get from the experianced Astrophotographers make our journey interesting and enjoyable .
