Nice work. It looks very M4.

ISO 200 sounds a bit low. Ideally one wants to set the ISO so that one photon equals at least one count in a 16 bit image. Setting it less than that is a bit like trying to measure the length of a grasshopper to the nearest kilometre. It might be worth trying a higher ISO. Use the highest ISO that doesn't burn out the stars in a single sub.

Keep them coming. Looking forward to your next image.
